Sponges 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)

 

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.
