Project kick-off; Lower Heterobranchia and Pyramidellidae of Norway

Since September 2023, a new taxonomic project started at the University Museum studying the biodiversity of sea snails (with shell) and sea slugs (without (visible) shell) in Norwegian marine habitats. This project is in a way a follow up from the “Sea slugs of Southern Norway” project between 2018–2020, but this time with a focus on poorly studied habitats including seagrass meadows, maerl coralline algae beds and landlocked fjords (“polls”). The target groups of this project are tiny sea snails of just a few millimeters, which are part of a group called “Lower” Heterobranchia and Pyramidellidae (Image 1) that together with the former ophistobranchs (e.g. the sea lugs), and pulmonates (slugs and land snails) form the Heterobranchia, one of the main evolutionary lineages of the Gastropoda.

The diversity of these tiny sea snails is poorly understood in Norway. Currently, nine families are known in the country: Acteonidae, Cimidae, Mathilidae, Murchiconellidae, Omalogyridae, Rissoellidae, Tjaernoeiidae, Xylodisculidae and Pyramidellidae (Høisæter 2014), but their small size and similar shells make it challenging to identify the species. During this project these sea snails will be studied in Norway for the first-time combining DNA barcoding and morphology. Sampling will be based on the use of dredges, grabs, and snorkeling by collecting the substrate they live on.

Pyramidellidae are ectoparasites and are often found living on other molluscs or other marine invertebrates, but also on soft sediments. The University Museum of Bergen has already a good collection of “Lower” Heterobranchia and Pyramidellidae from Norway, but a large part of this material is not suitable for DNA extraction due to the original fixation methods based on the use of formaldehyde. Therefore, after the first months of cataloguing the “old” collection and setting up protocols for DNA extraction, we finally set out in February to collect fresh material. We visited two different sites around Bergen to try out collecting specimens by snorkeling and test the efficiency of a recently acquired portable hand-dredge (Image 2).

Our first fieldwork day took place at the Marine Biological Station of UiB at Espegrend. The field station is a convenient place as it features a fully equipped laboratory (Image 3), and just in front of the station there is a seagrass meadow dominated of Zostera marina. This eelgrass is often found in shallow and sheltered coastal areas between 0.5 m to 10 m depth on flat sandy bottoms. Seagrass meadows are diverse and productive and can harbor hundreds of associated species from many different groups of animals. One team member swam with the dredge over the seagrass meadow and dropped it about 30 m from the shoreline, while the other team member pulled it back by hand. In addition, substrates like algae, blue mussels, and ascidians were hand-picked by snorkeling.

These efforts yielded the first specimens, namely the “Lower” Heterobranch species Ammonicera rota (Image 4) and the sea slug Elysia viridis (Image 5).

During our second sampling event, because of bad weather conditions with strong southern winds, we decided to visit a sheltered popular swimming area (although at this time of the year not so popular!) located north of Bergen called Helleneset (Image 6). Helleneset is a rocky shore area rich in algae and kelp with sand flats in between.

This time the algae and kelp mats collected by snorkeling in ziplock plastic bags did not yield much, but a close examination of the sand (with help of stereomicroscopes) collected again with the hand-dredge revealed the presence of many little gastropod snails. One of these little snails was our first Pyramidellidae; the identity is not yet completely confirmed, but it looks like Eulimella ventricosa (Image 7).

These two first samplings days were a good test for how we best can collect these snails which are small and in general a little abundant. The dredge is easier to operate with two people working together; one to deploy it and the other to pull it back to shore. Sandy samples yield better results if left to rest for several hours and even days in trays or buckets because anoxic conditions begin to form, forcing the animals to crawl out of the sediment.

This is just the beginning, if you want to be part of the journey of the diversity of “Lower” Heterobranchia and Pyramidellidae in Norway, we will be regularly updating stories and findings on this channel, and our social media accounts @SeaslugsofNorway (both Instagram and Facebook), see you there!

One Ocean Week 2024

the banner for OOW seen outside the University museum

From April 13th to 19th 2024, the Ocean City of Bergen celebrated the ocean even more than usual(!) in a happening called One Ocean Week (OOW).

One Ocean Week held conferences, meetings, workshops and activities – aiming to pioneer a sustainable use of the ocean.

The marine group at the University Museum was a prolific participant during the event, here are some of our contributions!

 

 

Anne Helene was invited to give the opening talk at the reception in the Aula, placing the Museum and Bergen into the heart of the Norwegian ocean exploration beginning with “The Norwegian North-Atlantic Expedition 1876–78”.

For our “Meet marine biologists from the University Museum” we brought with us five activities focusing on different areas of research that we do.

We had:

  • Sharks (see SharkReferences.com for more), with a shark tooth quiz, info about sharks in Norway, and the chance to see shark skin up close.
  • Bipolar animals (project Pole2Pole) where people could explore the distribution of animals that occur in one- or both- of the poles, and learn more about why that may be the case
  • Polychaetes (project MAnDAriN) with a quiz of trying to match images of colourful bristle worms to their common names
  • A task on Jellyfish parasites(!) (project ParaZoo) where you were to diagnose which parasite our unfortunate jellyfish suffered from, and finally
  • Moss animals (project NorDigBryo) where you could learn more about these animals, see them up close, and pick up a booklet with fun facts and some riddles to solve.

    At the Natural History Museum, our researchers offered free talks on topics of their choice; one talk every day (Tues-Fri). The topics covered here were:

    Who eats whom? Marine worms with jaws – delicious and dangerous! (Nataliya)
    Jellyfish in Norway – mostly harmless or murderous monsters?     (Aino)
    Sharks of Norway     (Nico)
    Elusive biodiversity: a journey through the less known but most exquisite groups of marine animals (    Manuel)

My internship at the University Museum of Bergen (Alina)

Hi, I am Alina Lösing, a bachelor’s student from Germany with the great opportunity to join the Cnidaria and Ctenophora team from the University Museum of Bergen for a 6 weeks Internship. This experience was not only a chance to further strengthen my passion in marine biology but also very helpful to gain valuable insight into research and museum operations.

During my time at the museum, I had the chance to join various projects of Joan J. Soto-Angel, including POLE2POLE (Horizon 2020, MSCA) on bipolarity, and Artsprosjektet NoAH (Artsdatabanken) on Norwegian Arctic Hydrozoa. I even had the honor to contribute a small part to it! I focused mostly on the polyp of Stegopoma plicatile, a supposedly widely distributed species present also in both Arctic and the Antarctic waters.

Figure 1: Living specimen of Stegopoma plicatile collected during the OceanX cruise at 240 m depth (Pictures: Joan J. Soto-Angel)

The first step was to take pictures of the different specimens that were sampled and categorized as Stegopoma plicatile. Further I took pictures of many other species of Arctic hydrozoan polyps and hydromedusae. I learned some useful tricks with the camera while photographing the different species of polyps and medusae.

Part of the project is developing a reliable workflow which allows for a morphological distinction between polyps belonging to potentially different species previously defined molecularly from different areas worldwide. Therefore, I spent a lot of time working with the microscope collecting data which can be crucial to refining the morphological differences between different species. I measured length and width of 380 nematocysts!

Furthermore, I underwent training in tissue sampling, a crucial step in preparing the samples for DNA sequencing. It’s all about preventing tissue contamination! Moreover, I had the opportunity to visit the DNA Lab, where I received instruction in their specialized techniques for DNA extraction, PCR, and electrophoresis. Many thanks Cessa for your time and dedication!

The highlights of my internship were of course both sampling trips I got to attend on board the Research Vessel Hans Brattstrøm. On the ship I learned a lot about the specific sampling methods for these incredibly delicate invertebrates. Despite experiencing a bit of seasickness the first time, I assisted with net deployment, sorting the animals, and collecting water samples from different depths.

Apart from an amazing Jellyfish Team, Bergen has many more attractions to offer. I highly recommend packing your hiking boots for your next visit, as the surrounding mountains offer breathtaking scenery. And if you share my passion for the ocean, a visit to the Nordnes Sjøbad is a must. Here you can take a refreshing dip in the frosty ocean before warming up in the heated saltwater pool.

 I would like to take a moment to acknowledge Joan’s invaluable contribution to my internship at the University Museum of Bergen. Joan’s dedication and extensive knowledge have made my experience truly unforgettable.

Student visits – Ellisiv and Maria

A guest post from two of our MSc students (in this case co-supervised with NTNU) who were here on a research visit for three weeks in January 2024. 

We are Maria Buhaug Grankvist and Ellisiv Tomasgard Raftevold, and for the past three weeks we have been visiting the University Museum in Bergen to work on our master’s projects. It’s been a lot of fun, a lot of hard work and very useful, as the Bergen University Museum really is the place to be when you’re working with marine invertebrates.

Both our theses focus on marine invertebrates, but two different phyla. Maria is working with cyclostomatid Bryozoans, while Ellisiv looks at Polychaetes. We write our masters for the NTNU University Museum in Trondheim in collaboration with the University Museum in Bergen and the projects “Digitization of Norwegian Bryozoa” (NorDigBryo) and “Marine Annelid Diversity in Arctic Norway” (ManDAriN). Keep reading, and you will learn about our projects and what we recommend to do when visiting Bergen!

Ellisiv’s marine annelids:
I’m Ellisiv and in my master’s thesis, I study a marine Annelid or Polychaete genus called Flabelligera within the family Flabelligeridae. Flabelligerids are mostly benthic and can be found from the intertidal zone down to the deep sea. They like living in the sand or mud, or under rocks, and they can be quite small and have sediment camouflage or a completely transparent body and outer sheath and may therefore be quite hard to find. If you do find them they are quite cool to look at, and if they are transparent, you can see their internal organs and green circulatory system. Their most prominent character is the cephalic cage, which is a circle of bristles around their mouths forming a kind of cage. In the ecosystem, these animals have an important role in that they for example eat the marine snow that falls to the bottom of the oceans so that it can be recycled back into the food chain.

Flabelligera affinis, a species within this genus was until recently thought to be only one species and was thought to have a worldwide distribution. This, however, was shown not to be true when Salazar-Vallejo 2012 restricted F. affinis to arctic areas and reinstated F. vaginifera which was previously synonymized with F. affinis, and proved that it was at least two different species sorted into one. Also looking at the material we have in the museum collections and DNA samples it was suspected that there are multiple different species sorted into F. affinis.

This is the problem I am trying to solve in my master’s thesis, and to do this I need to study the specimens found in the museum collections that are sorted to F. affinis and look at their different morphological characters and sort them into groups. This is mostly what I have done in Bergen. However, these species are very similar, and sequencing their DNA to look at their relatedness is a very useful addition to the morphology. Hopefully, I can get a step closer to solving this taxonomic confusion in my master’s and we can get to know how many species are hiding within Flabelligera.

Maria and the bryozoans:
I’m Maria, and for my master thesis I’m recording the diversity of bryozoan species within the order Cyclostomatida in Norwegian waters (meaning off the coast of Norway, the arctic ocean and some nearby areas). In addition to creating a checklist of recorded species, I’m mapping out their geographic and bathymetric distribution. In short, I’m trying to provide an answer to the question: What species of Cyclostomatida do we have, and where do they live?

There are two main reasons for studying this particular phylum in my thesis. First, they are strongly understudied, and according to a report published by the Norwegian Taxonomy Initiative in 2021, our understanding of bryozoan distribution and ecology is weak and unsatisfactory, even with “essential knowledge gaps” in some areas.
The second reason explains why it’s an issue that we know so little about these animals: They are majorly important for many marine ecosystems! Nearly all bryozoans are colonial, so even though the zooids (term for an individual animal in a colony) is only 0,1 – 0,5 mm long, the colonies can be as much as half a meter tall or wide! Many of the colonies have intricate shapes supported by heavily calcified structural zooids, providing habitats for a wide range of other animals. In this way, the bryozoans promote biodiversity in much the same way corals do, but they are far less known and barely protected by law like their coral counterparts.

To protect these beautiful colonial creatures we first of all need to know them better. Mapping the actual diversity and distribution of Norwegian bryozoans is far too large a task for a two year master thesis, but my thesis will hopefully contribute to the final results of the NorDigBryo project.

DNA sequencing
For both our theses we use an integrative approach, combining the morphology (what we see/the physical traits of the animals) with genetic sequence data. DNA sequencing is one of the things we got to do in Bergen, and it was very interesting to see how this is done from start to finish. We got to extract the DNA, use PCR and specific primers to amplify the DNA string of interest and gel electrophoresis to test if the prior methods worked.

For the successful sequences, we got to try the Sanger sequencing method, and it is very exciting to get to use some of our own sequences in our theses.

When in Bergen:
You’d might think that when we finish long days at the university museum, looking at marine invertebrates from dusk till dawn, we would go and do something completely different when the weekend comes. You’d be wrong!
In our spare time in Bergen, we went to see the University Museum of Natural History and were there almost from when it opened until it closed because there were so many interesting exhibitions. There are so many beautiful creatures on the planet, many of them and the story of how they evolved, you can learn about at the museum. We of course especially loved the “deep sea-room” where we would sit for a long time while watching a cephalopod swimming around deep sea sulfur vents..soothing.

World Jellyfish Day pt 2: OceanX – gelatinous predators

This summer, researchers from the University Museum of Bergen participated on a research cruise onboard R/V OceanXplorer, the research vessel of OceanX. OceanX is a nonprofit ocean exploration organization founded by Mark and Ray Dalio in 2018. The organization’s mission is to “explore the ocean and bring it back to the world”, and the vessel is designed and constructed by OceanX to conduct ocean exploration, scientific research, and document stories of discovery to share with the public worldwide in a state-or-the art way.

One of the outcomes of the cruise was this amazing short documentary focusing on the work Aino Hosia and the rest of our “Team Jellyfish” (Joan & Luis) were doing onboard.

Today being the World Jellyfish Day, we wanted to share it here – enjoy!

November 3rd. World Jellyfish Day!

Today is World Jellyfish Day, and we at the Cnidaria and Ctenophora team have prepared for the occasion a poster featuring some of the beauties we have collected during the recent years in the context of our Artsdatabanken and EU MSCA projects.

Happy World Jellyfish Day everyone!

Jellyfish are normally associated with nuisance and pain, and often considered a plague that is taking over the oceans, diminishing its resources, hindering industrial operations,  and making beaches less attractive for tourists. However, jellyfish are not only an integral part of healthy pelagic ecosystems, but also key players in planktonic communities. Until recently, their fragile and soft bodies had obscured our knowledge on their true abundance and key role in ocean ecosystems, as regular sampling methods tend to overlook them, giving the false impression that they are ecologically irrelevant. However, recent evidence have shown that they are an important part of the regular diet for many fishes and invertebrates, both while swimming in the water column, and once their remnants fall to the seafloor, transferring a significant amount of carbon to the deep sea. Actually, jellyfish are the top predators in the food web at planktonic scale, comparable to lions in the savanna or great white sharks and killer whales in the open ocean.

10th International Workshop of the Hydrozoan Society

Earlier this year, the Cnidaria and Ctenophora group at UMB organized the 10th International Workshop of the Hydrozoan Society. The event was a success, and we asked visiting researcher Marta Gil to tell us a little more about it.

This is what Marta, who is currently collaborating in our Artsdatabanken projects ParaZoo and NOAH, has to say:

Hello to everyone!

I’m Dr Marta Gil, a researcher at the association Ecoafrik and a member of the Marine Zoology Group at the University of Vigo, Spain. This spring I began a research stay at the University Museum of Bergen to collaborate with Dr Luis Martell on project PARAZOO. I have visited the museum several times, but this visit had a special meaning for me. This year, in May, the 10th Workshop of the Hydrozoan Society was celebrated, organised by the Cnidaria and Ctenophora Group at the Department of Natural History, so I took advantage of my stay in the city and decided to attend.

Three images together: one showing the (taxidermied) birds in the staircase of the museum exhibition, one showing participants studying the exhibits in the whale hall - a whale skeleton can be seen over them, and a photo from the reception where the society president is welcoming everyone

Welcome and icebreaker at the University of Bergen Museum of Natural History

This was my first time at this event and I must say it was a very rewarding experience, I don’t think I could have enjoyed it more. We were welcomed by the organisers at the public collections of the Natural History Museum, which was open only for the occasion, creating a fantastic atmosphere to meet the participants and many of the hydrozoan experts.

Over the next three days, we listened to talks from students who are just starting as well as presentations from established researchers who have been working with hydrozoans for years. We have had great speakers such as Dr. Nicole Gravier-Bonnet, Prof. Carina Östman, and Dr.Gill Mapstone; and how to forget the enthusiasm of Prof. Paul Bologna’s group, all the questions and remarks from Dr. Dhugal Lindsay, and the sampling demonstration from our Japanese colleagues Gaku Yamamoto and Aya Adachi? The discussions that took place after each talk and the engaging poster session made this workshop more than a simple scientific meeting, it was a group of friends talking about their favourite animal group: hydrozoans!

A collage of images showing participants presenting at the venue

The conference part of the Workshop brought many interesting talks from a wide array of topics, together with fruitful and interesting discussions and networking.

Several images showing people studying large (A0) scientific posters presenting results of their research and projects.

There was a dedicated poster session (and catering) to further discuss about hydrozoans in a more relaxed environment. Many great projects and preliminary results were presented!

After the talks and presentations were over, the sampling part started, which was the most fun for me! We were able to sample benthic hydroids and pelagic hydromedusae and siphonophores on board the Emiliania and the R/V Prinsesse Ingrid Alexandra, and we later studied them at the Espegrend Marine Biological Station. This part gave us the opportunity to learn and share knowledge, techniques and very useful tips from other experts to study hydrozoans throughout their life cycle.

Snapshots from fieldwork, where people are collecting plankton and benthos from ship and shore

Two busy samplings days followed the conference part, where we all exchanged our expertise on sampling, handling and culture techniques. This were a couple of very productive sessions.

To round off an amazing week, on Saturday morning we visited the UNESCO World Heritage Site at Bryggen, where we learned about the history and traditions of Bergen. At sunset, we took the cable car up to Mount Ulriken and, after enjoying the incredible views, we held the award ceremony and the election of the new president of the Hydrozoan Society, who was unanimously elected: Dr. Lucas Leclère!

Snapshots from social activities throughout the event; shows people in historical Bryggen, as well as up the city mountains around Bergen

The social activities included a visit to Bryggen, an excursion to Fløyen, and the conference dinner in the top of Mount Ulrikken. The best student presentation awards were given and the new President of the Hydrozoan Society was elected. Exciting times ahead!

The third group picture we took in just a few days, this time with an incredible view of the city of Bergen as a background.

I would like to close this chronicle by thanking UMB’s Cnidaria and Ctenophora group: Aino Hosia, Luis Martell and Joan Soto, for their incredible work in coordinating the presentations, transfers and field work and for hosting such a rewarding event. I would also like to mention the great work done by all the students of the group, who helped organize the meals on the sampling days and other various activities. Thanks to all of them, the rest of us simply enjoyed the week.

It was definitely an experience worth repeating. I’m already looking forward to the next workshop in France!

The Cnidaria+Ctenophora Research group at the PRIMALearning Jellyfish Workshop in South Africa

On the 12th of February at the crack of dawn, we had the amazing opportunity to go to Cape Town to attend a Jellyfish workshop. The “we” in question are the three authors of this blog post: Vincent, Vetle, and Håvard. We are master students all working with jellyfish-related topics, and some would go as far as to call us jellyfish enthusiasts. Our work is part of the museum’s Artsprosjekter NorHydro and ParaZoo, and we were happy to represent the invertebrate collections and UMB at this event.

The workshop, held at the Iziko South African Museum, was organized by PRIMALearning and was a collaborative initiative between the University of Bergen and the University of Western Cape. This gave the three of us, accompanied by a few other UiB students not affiliated with the University Museum of Bergen, the chance to visit Cape Town. Some of us for the first time.

On the first day of the workshop, we were greeted outside the museum by Mark Gibbons and his PhD student Michael Brown who was the representative from UWC and would be teaching parts of the workshop. With them was also Anne Gro Vea Salvanes as the representative for PRIMALearning and the University of Bergen, she was also joined by our own UMB scientists Aino Hosia and Luis Martell, who were also part of the teaching team.

The first day included introductions from all the participants, and we got to know each other bit better. We also got a brief introduction to the world of jellyfish and their taxonomy before the night ended with a delicious dinner together with all the participants.

The second day started with lectures about the large or ‘true’ jellies (Scyphozoa), before we got to get our hands dirty looking at preserved samples of jellyfish. We were met with a broad diversity of scyphozoans that was passed around between the students so we would get a shot at identifying them.

We examined fixed material of scyphozoan jellies representative of the three major groups within the class:

 

The rest of the day after the workshop was spent at the beach, enjoying the sun and local wine. Cape Town is called the windy city, and it did deliver on its name, but nothing could stop the sun-deprived Norwegian students from going outside to soak up some rays.

The third day was Hydrozoa day 1, a topic dear to our hearts and it was taught by our own MSc supervisor Luis Martell. Some of us were a bit tired this day because we decided to climb Lion’s head mountain before the workshop started to see the sunrise.

But this did not stop us from eagerly working with the preserved hydrozoan samples we got to look at. We identified all hydromedusae and siphonophores with the help of a stereomicroscope:

Day four was box jellies (Cubozoa) day, a class neither of us was very familiar with. So we were excited to learn about these unknown and sometimes dangerous animals.

Luckily the animals were less deadly when preserved and we could therefore touch them while identifying them.

 

 

 

This day ended early so we took the opportunity to get down to Simon’s Town were we spent the rest of the day looking at the local penguins and wildlife at the beach.

On our last day, we were introduced to the alien world of siphonophores by our own Aino Hosia. These animals are close to Håvards heart (if you ask him on a good day).

They were a nice ending to an awesome workshop, and we can honestly say now that our interest for jellyfish has grown, and we look forward to seeing even more of them in the future.

On February 19th the vacation/business trip was unfortunately over for Vetle and Vincent and they had to pack their bags and prepare to leave Cape Town and head home to Bergen, while the “slightly” more fortunate Håvard stayed behind in the windy city to enjoy a few more days of leisure.

We want to thank PRIMALearning for arranging the workshop, the University of the Western Cape for hosting and providing us with samples to work with, the Iziko Museum of South Africa for the location as well as providing refreshments, and to the University of Bergen for arranging accommodations. Also, a very special thanks to all the lecturers who presented and were very patient with us during the lab work.
