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. Item Type: Image Title: Nereis gracilis Copyright: SERPENT project Species: Nereis gracilis Behaviour: Motile and likely to be an omnivorous scavenger Site: Atlantic -- Norwegian -- Dalsnuten Site Description: Seafloor Depth (m): 1452 Latitude: 66 deg 34' 33" N Longitude: 3 deg 32' 46" E Countries: Norway -- Norwegian Sector Habitat: Benthic Rig: Aker Barents Project Partners: Shell, Aker Drilling, Oceaneering ROV: Magnum 142 Deposited By: Miss Moira MacLean Deposited On: 23 February 2011

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.
