terns of color on various parts of the body, including 

 scarlet branching gills. Tubicolous forms, especially, 

 exhibited a wide range of color patterns on their ten- 

 tacles and branchiae. 



A few species are commensal on sponges and echino- 

 derms, but more often they themselves are the hosts to 



commensal partners, for example the Chaetopterus- 

 Pinnixa (Decapoda) relationship and the Clymenella- 

 Listriella (Amphipoda) relationship. 



Annelids occurred in 1,034 samples (96% of total), 

 their density averaged 425/rrr,and their biomass aver- 

 aged 17.4 g/m 2 (Table 5).
