How different are the animals in this family! To put it simply, there are three types:
-
bivalves, the so-called "shells", such as oysters or scallops,
-
cephalopods, such as octopus, squid or cuttlefish,
-
and last but not least, the gastropods which, under the sea, display a profusion of shapes and colors to delight all divers, whether photographers or not.
They may have a shell (cones, snails) or not (slugs). The main part of this page is devoted to nudibranchs, incredibly varied slugs. Their resplendent colors are a defense: they warn predators that they are indigestible, sometimes even toxic.
