Description
Body with 65 to 90 or more segments and 47 to 87 pairs of elytra; on the posterior-most region, the elytra occur on every segments (rather than on alternating segments, as in most Polynoidae). The tips of the notopodia and neuropodia, and the ventral cirri, all have numerous papillae. Some neurochaetae have forked tips (with 2 terminal teeth of similar size).[2]
Although Brychionoe currently contains a single described species, an additional record of an unidentified species in this genus was reported from the Indian Ocean by Serpetti et al. (2017).[3]
Biology and ecology
Brychionoe karenae has a commensal relationship with the antipatharian coral, Leiopathes sp..
