'''''Bornella''''' is a [[genus]] of [[sea slug]]s, specifically [[Dendronotida|dendronotid]] [[nudibranch]]s 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 [[hydroid (zoology)|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.<ref>Pola, M., Rudman, W. B. & Gosliner, T. M. (2009) Systematics and preliminary phylogeny of Bornellidae (Mollusca: Nudibranchia: Dendronotina) based on morphological characters with description of four new species. Zootaxa, 1975, 1-57</ref><ref>Rudman, W.B., 2009 (Jan 27) [http://www.seaslugforum.net/find/22194 ''A revision of the genus ''Bornella.] <nowiki>[Message in]</nowiki> Sea Slug Forum. Australian Museum, Sydney.</ref>
==Description==
Their body is covered with cerata-like dorsal and lateral outgrowths, with finger-like branches. They have an attached cluster of  [[gill]]s. 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.
