Bornellidae
The family Bornellidae
includes species with very narrow, elongate
bodies and 4-6 pairs of dorso-lateral cerata-like projections, each
bearing a feathery gill on the medial side. The long rhinophores reside
within sheaths that have elongate papillae along their edges. Most
bornellids are capable of actively swimming if disturbed. They feed on
hydroids. Three species are known from Hawaii in the genus Bornella. |
