Description

[edit]

The shell of Galeodea echinophora can reach a length of 50–110 millimetres (2.0–4.3 in).[1] The shell is globular or oval, with a large body whorl. The surface of the shell is yellowish-brown. The aperture is wide, with denticulate lips, a curved siphonal canal and a large columellar edge. Tubercles are quite variable, usually not very pronounced and may be entirely absent.[5] These mollusks are carnivorous and eat mostly echinoderms, especially Echinocardium cordatum.

Distribution and habitat

[edit]

This species can be found in the Eastern Mediterranean Sea and in the North Atlantic Ocean, mainly in Western Africa.[1] It lives on sandy and muddy bottoms over 10 m in depth.
