The anomiidae (Anomiidae) are a shell - Family from the order of Pectinida .
features
The housings are unevenly hinged and lie with the right flap on the floor; they are attached to the ground by a calcified byssus . The byssus passes through a deep, almost closed bay on the dorsal margin in the right valve. The hole only appears after the housing has been detached from the surface. The flaps are very flat and even trace the substrate surface a little on the upper flap. The lower right flap is often very thin and translucent, while the upper left flap has a solid shell. The byssus muscle attaches to the left upper valve with one or two strands, which leave clear marks in the shell. In addition, there is the more or less large sphincter muscle, which attaches near the byssus muscle (s) and also forms a scar on the inside of the shell. The lock edge is straight and toothless.
Geographical distribution and habitat
The saddle clams are found in all seas worldwide. They live are attached to the ground by a calcified byssus. Algae, mussel and snail shells and the shells of crustaceans are also used to fasten the shells.
