Polystira albida, common name white giant turris, is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.

Distribution

P. albida can be found in Western Atlantic waters, ranging from the eastern coast of Florida south to Brazil.

Description

Shells of Polystira albida can reach a size of 44–127 millimetres (1.7–5.0 in). These large shells are slender, fusiform, with a narrow and long aperture and a white external surface.

Habitat

These tropical benthic gastropods live at depths of 15 to 229 m.

Life cycle

Embryos develop into free-swimming planktonic marine larvae (trochophore) and later into juvenile veligers.
