SEA SLUGS Aeolids have frilly cerrata, often in two rows at the sides.

Major groups of Nudibranchs include Dorids, Aeolids, Dendronotids and Armina. Sea Slugs only have a shell for one day in the larval stage which is then lost.



Recent research is making many more fascinating discoveries about Nudis. All of them are hermaphrodites. Many are brightly coloured to advertise the fact that they are toxic. Some have camouflage that is so good that they are virtually invisible. Some can shed their mantle or cerrata to escape predation.
