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)
Except for those species verified
by collection (indicated by *), 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.
