Distribution

P. albida can be found in Western Atlantic waters, ranging from the eastern coast of Florida south to Brazil.[2][3][4][5]

Description
A shell of Polystira albida

Shells of Polystira albida can reach a size of 44–127 millimetres (1.7–5.0 in).[3][4] 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.[4][6]

Life cycle

Embryos develop into free-swimming planktonic marine larvae (trocophore) and later into juvenile veligers.[6]
