Nudibranch ~ up very close and very personal @ Cyrene Reef, Singapore

According to wildfilms.blogspot.com/2008/07/cyrene-walk-with-ura.html, it could be "some sort of Dendrodoris, possibly Dendrodoris tuberculosa, see entry on Dr Bill Rudman's Sea slug forum (seaslugforum.net/factsheet.cfm?base=dendtube)." There seems to be great potential for colour variation in this species.

See also wildfilms.blogspot.com/2008/04/earth-day-with-echinoderms-at-pulau.html for what could be a different colour variation of this species.

The specimen in the video was about 5 inches long and found in a sandy area on Cyrene Reef off the West Coast of Singapore in an area surrounded by a container port and petrochemical hub.
