Les invertébrés marins du golfe de Gascogne à la Manche orientale

The guide describes, per family, over five hundred species of invertebrates likely to be picked up by a trawl. Broken down into eight divisions, these species belong mainly to the groups of crustacea decapoda (prawns, hermit crabs, galatheids and crabs), molluscs (gasteropods, bivalves, cephalopods) and echinoderms (starfish, sea urchins, sea cucumbers). A few data sheets have supplementary boxes giving the characteristics of species of the same genus. The book is illustrated with over one thousand photos, mostly in colour, and line drawings.
