|Kingdom Animale | Phylum Mollusca|
They have unsegmented bodies which display a great diversity in form. A large muscular foot and mantle (wide body fold) characterise the phylum. Many secrete shells.
They can roughly be divided into three major classes:
Bivalvia (bivalves), and
Cephalopoda (squids and octopuses).
