Phalium glaucum, common name the grey bonnet or glaucus bonnet, is a species of large sea snail, a marine gastropod mollusk in the family Cassidae, the helmet snails and bonnet snails.[1]
Distribution
This species is widespread in the Indo-Pacific, from Eastern Africa (Madagascar, Mozambique, Tanzania) to Southern Japan and Melanesia. [2]
Habitat
This species lives on sandy bottoms with seagrass meadows, in intertidal and shallow subtidal areas to a depth of about 10 m. [3]
Description
Shell of Phalium glaucum can reach a length of 60–147 millimetres (2.4–5.8 in).[2]
These shells are helmet shaped with a large body whorl and tiny spires. The surface of shell is smooth and uniformly greyish or pale brown. The molluscs have a white body and a large yellowish or whitish foot which is edged in reddish brown. The operculum is bright yellow and fan-shaped.
