As part of the celebration of the first decade of WoRMS – the World Register of Marine Species, ten of the most astonishing new species from the big old blue is given a special presentation here.

Door # 6: Stuffed Syllid

Todays calendar critter is a Trypanosyllis sp. – a undescribed species from the genera Trypanosyllis in the family Syllidae. It most closely resembles a species described from the Mediterranean Sea. The Norwegian species is common in coral rubble, and has been assumed to be the same species as the one described from the Mediterranean. Genetic work reveals that these two are in fact separate species, and thus the Norwegian one is a new species awaiting formal description and naming. (If you read Norwegian, you can learn more about how species are described and named here: Slik gir vi navn til nye arter).

This specimen was collected, identified and photographed by Arne Nygren during our field work in Sletvik as part of his work on cryptic polychate species in Norway.

Syllids have opted for a rather fascinating way of ensuring high fertilization rates; something called epitoky: they asexually produce a special individual – the epitokous individual – from their bodies, and release this to go swimming in search of a mate. In the photo you can see that the female reproductive body (epitoke) is filled with orange eggs and has its own set of eyes, close to the middle of the animal. This section will break away from the mother animal and swim away in search of a male reproductive body to reproduce with. The mother animal will then grow a new female reproductive body.

A new polychaete species!

Meet Ampharete undecima, a new species of polychaete (bristle worm) that we recently described:

The species has been decribed based on material collected by the University of Bergen in the Nordic Seas in the 80s, and from samples collected by MAREANO in more recent years. It occurs in deep waters between 600 and 1650 meters depth, and has a broad distribution. The type specimen of the species is from a location that MAREANO sampled in 2009.
