Some [[Opisthobranchia|sea slugs]] are very brightly colored. This serves either as a [[Aposematism|warning]], when they are [[poisonous]] or contain [[stinging cell]]s, or to [[camouflage]] them on the brightly colored [[hydroids]], [[sponge]]s, and seaweeds on which many of the species are found.{{citation needed|date=February 2025}}

Lateral outgrowths on the body of [[nudibranch]]s are called [[cerata]]. These contain an outpocketing of [[digestive gland]]s called the [[Diverticula (mollusc)|diverticula]].{{citation needed|date=February 2025}}
