Aporrhaids are commercially important, especially in traditional fisheries.[4]
Description
Aporrhaids have a large lip with finger-like extensions, and a small
operculum. They do not have movable eyes. Instead, their eyes are fixed at the base of each tentacle.[5]
The mollusk has one narrow foot, which renders its motion interrupted as the foot must raise the shell a tiny bit in each single movement, simultaneously pushing it forward. The motion must be repeated again and again for the mollusk to travel.[6]
Habitat
Aporrhaidae live on muddy and sandy bottoms, sometimes in very large populations.
