Aristeomorpha foliacea

Aristeomorpha foliacea Commonly called the big red shrimp, Aristeomorpha foliacea is caught in considerable quantities by trawlers on the coast of Algeria. It is caught all year round at depths exceeding 250 m. Very popular in Europe, it constitutes the majority of Algerian fish exports to this continent. Pinna nobilis Commonly called the sea ham, Pinna nobilis is the largest bivalve mollusc in the Mediterranean. It lives buried vertically in shallow mud. Sports divers appreciate its internally pearly shell. The filaments of its byssus are spun in southern Italy where they are used to make gloves. Retepora cellulosa Retepora cellulosa or Neptune's lace is a bryozoan which forms small colonies in the shape of corollas. It is frequently found in Algeria, at shallow depths, in poorly lit rocky places. Corallium rubrum Commonly called red coral, Corallium rubrum belongs to the coelenterates phylum, which makes it similar to jellyfish. It differs from the latter by its life fixed on the seabed and by its limestone skeleton. It constitutes colonies that are still found quite frequently on the Algerian coasts, in rocky areas located at depths of 20 to 50 m. Its skeleton, an extremely pure red, is worked into jewelry. It is used to decorate Kabyle jewelry.
