Aporrhais pespelecani

Aporrhais pespelecani, common name the "pelican's foot" (or more precisely "common pelican's foot" to distinguish it from congeners), is a species of sea snail, a marine gastropod mollusk in the family Aporrhaidae.

Until the early 20th century the scientific name was usually written with a hyphen and spelled "pes-pelicani".

[1] The specific name pespelecani is Latin, and means the same thing as the common name: "pelican's foot".

This name is based on the shape of the three-pointed (or four-pointed) expanded outer lip of the adult shell, which resembles the webbed foot of a sea bird such as a pelican.

This species of sea snail lives below the low tide level, in the sublittoral zone, from 10 to 130 m depth, on mud or muddy sand.
