Summary

Description
Français :

Les nudibranches sont des mollusques gastéropodes, caractérisés par leur absence de coquille, ce qui leur vaut le nom de "limace de mer".

Aeolidiella alderi, ou eolis d'Alder, est un petit nudibranche éolidien présent en Atlantique Nord-Est et en Méditerranée, à faible profondeur. Pouvant atteindre une longueur de 37 mm, son corps a une forme large et aplatie, allant du blanc au orange.

Il se caractérise essentiellement par sa première rangée de cérates (ou papilles dorsales) blanches, qui forment une collerette. Les cérates sont généralement courts, plus grands au milieu que sur les bords, avec une pointe plus claire.

English:

Nudibranchs are gastropod mollusks, characterized by their lack of a shell, which earned them the name "sea slug".

Aeolidiella alderi , or Alder's eolis, is a small aeolian nudibranch found in the Northeast Atlantic and the Mediterranean, at shallow depths. It can reach a length of 37 mm, and its body has a broad, flattened shape, ranging from white to orange.

It is mainly characterized by its first row of white cerata (or dorsal papillae), which form a collarette. The cerata are generally short, larger in the middle than on the edges, with a lighter tip.
