Observed
in video surveys (ROV Jason in 1998 and 1999 and ROV JasonII in 2003 and 2004) and/or
camera sled/otter trawl transects (in 2003)
These classifications are best
guesses and subject to change. Classification
was checked first with Tree of Life
and then with European Register of Marine
Species in June 2006.
