Pasajes, Pais Vasco-Spain


Dotted Sea Slug - Peltodoris atromaculata

The Dotted Sea Slug (Peltodoris atromaculata) is also known as the little Swiss Cow in Spanish (Vaquita suiza).  It is a large Mediterranean sea slug that can grow up to 120 millimeters long.  It is quite common in Mediterranean shallows where it reproduces among the lower shore in spring and summer.  

It is easy to identify with its white body and dark brown spots.  It has two head tentacles and branching gills in a ring on its back.  Feeding on sponge, it accumulates natural chemical products and stores then in its digestive gland.
