Door #20: How many undescribed bristle worms live in Australian waters?

The answer is, of course, “we don’t know”. But we *can* say that Australian polychaete fauna is largely undescribed. As an example, 91 new species and 67 new records of polychaete worms were found in the vicinity of a single small island at Great Barrier Reef as a result of a joint effort of 16 polychaete experts that spent two weeks at the Lizard Island Research Station of the Australian Museum in 2013.

Not only the Great Barrier Reef polychaete fauna is poorly studied, various areas of Australian east coast apparently also have numerous undescribed species especially in the deeper waters. Here you can see few examples of recently described new species of bristle worms from Australian.
