Bornella is a genus of sea slugs, specifically dendronotid nudibranchs in the family Bornellidae.
There has not been much research on this genus. Their biology is mostly unknown, except that they seem to feed exclusively on hydroids.
Distribution
These nudibranchs occur in the Indo-West Pacific. In addition there is one species in the tropical eastern Pacific, and one species in the western Atlantic.[1][2]
Description
Their body is covered with cerata-like dorsal and lateral outgrowths, with finger-like branches. They have an attached cluster of gills. Their rounded head shows on each side of the mouth a tentacle, with tiny finger-like papillae. The sheath of the rhinophore stands high and resembles the dorsal processes. Feeds on hydroids.
The various species differ in their color pattern and their number of dorsal and lateral outgrowths and the number of branches on their rhinophore sheath.
Anatomy
These nudibranchs are characterized by an unpaired oral gland.
In their genital system, the male duct is separate from the female duct.
