Aporrhaidae is a family of sea snails commonly called the "pelican's foot snails." The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[3] categorizes Aporrhaidae as marine gastropod mollusks in the clade Littorinimorpha.

Aporrhaids are commercially important, especially in traditional fisheries.[4]

Description

[edit]

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

[edit]

Aporrhaidae live on muddy and sandy bottoms, sometimes in very large populations.

Subfamilies

[edit]

Subfamilies in the family Aporrhaidae include:

Aporrhais from the Pliocene of Cyprus.

Genera

There are only two Recent genera:[7][8]
