the polyps of the corals. Or the association could be a 

 combination of these interactions. Shrimp were also fre- 

 quently seen on hydroids and sponges. 



Two other associations with corals were noted. One is 

 the occurrence of the ophuiroid Asteronyx loveni in colonies 

 of Paramurioea grandis. This association appears to be 

 obligatory in that no free-living A. loveni were ever seen. 

 The ophiurid could merely be using the coral colony as a 

 substrate such that it can be suspended in the water column 

 for feeding or it might actually prey on the coral polyps. 

 Another possibility is that it uses the coral as protection 

 from predation. The other association involves P. grandis 

 and the anemone Aotinauge verilli which is sometimes found 

 attached to the coral. Whether this association is obligatory 

 is not known. 



Other associations that were noted are between juvenile 

 crabs and fish and the large anemones found in shallow water. 

 These anemones are Cerianthus horealis , Boloaeva tuediae ^ 

 Aatinosayphia saginata and the large white anemone found in 

 Baltimore Canyon. The small crabs and fish appear to be 

 utilizing the base of the anemones for protection. Two species 

 of crabs Cancer borealia and Bathynectes superba and the rosefish 

 are most commonly seen in this association. This relationship 

 most frequently occurs between Canaer horealis and Cerianthus 

 horealis . A small galatheid crab was also seen crawling on the
