Description: The polychaete Nereis gracilis (Hansen, 1878). This motile species is known exclusively from deep
waters (range 930-2222 m) and has been recorded from the deeper parts of the Norwegian Sea, the Laptev Sea and
probably the Sea of Beaufort. As with many deep-sea species very little is known about its biology. Nereis gracilis is likely to be an omnivorous scavenger with the specimen from Dalsnuten being approximately 15 cm long.

I had never seen a worm quite this color before. The body can be bright green, blue-green or brown, and the parapodia lobes light in color. They can be up to 100mm in length, so this was a very "small one". It lives in mucus tubes amongst algal frond or holdfast, or in mussel beds. (Thanks to Marlin Harms for the species ID, as I only knew the genus). Marlin found this beauty. Great day we had, Marlin.
