Onchidoris bilamellata
''Onchidoris bilamellata'', common name the rough-mantled doris, is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Onchidorididae.〔Gofas, S. (2010). Onchidoris fusca (Müller O.F., 1776). In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database.

== Distribution ==
This nudibranch has a wide distribution, mostly in colder intertidal waters to a depth of about 20 m. It has been found in the North Atlantic and the North Sea from Britain and France to the Norwegian Sea, Iceland and Greenland; along the North American coast as far south as Connecticut. It has also been recorded in the North Pacific in the Bering Sea, and from Alaska south to northern California.
These sea slugs sometimes occur in abundant numbers during breeding time, swarming with over 1,000 individuals per square metre, as has been observed on numerous occasions.〔 Pelseneer P. (1922). 〕〔(【引用サイトリンク】title=''Onchidoris bilamellata'' aggregation in Maine, USA )〕 These swarms are all oriented in the same direction, determined by the flow of the tide. They follow each other at the same speed, forming columns, in different close-knitted rows.
