As aplysiidae refers to a family of opisthobranch (Opisthobranchia). In the neurosciences , the species Aplysia californica is an often used research object due to its large neurons . There are currently around 80 species in this family.

Way of life

All species are marine, one speaks of sea ​​snails . The genera are equipped with four tentacles and usually have a rather thin shell, which can also be partially receded. Algae are usually the main food of these snails.

Systematics

The Aplysiidae belong to the suborder broad- footed snails (Anaspidea), whose name comes from the fact that the small shell is covered by the two foot lobes. Only two superfamilies are assigned to the common snails, namely the Akeridae in addition to the Aplysioidea . The systematics of these snails was first researched in the 18th century on their occurrence in the Atlantic , by Linné in 1767 and Lamarck around 1800.
