Description
Bornella is a genus of dendronotid nudibranchs in the family Bornellidae. It occurs mainly in the Indo-West Pacific, with one species in the tropical eastern Pacific and one in the western Atlantic. The slugs feed on hydroids, and many can swim when disturbed.
Identification
The body is narrow and elongate, with four to six pairs of dorsolateral cerata-like projections with finger-like branches, each carrying a feathery gill on its inner side. The rhinophores sit in sheaths with elongate papillae along their edges, and the rounded head bears tentacles on each side of the mouth.
