Molluscs at the Hawaii-2 Observatory

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.
