Turbinella angulata, common name the West Indian chank shell or Lamp Shell, is a species of very large tropical sea snail with a gill and an operculum, a marine gastropod mollusk in the family Turbinellidae. [1]

The name "chank" for the shell of this species is derived from the word shankha, the divine conch or sacred conch, Turbinella pyrum, a closely related species from the Indian Ocean. [2]

These large reef-associated gastropods can be found in tropical environment on subtidal and offshore mud, on rock or sand beds, and on mangrove lagoons, at depths of 0 to 45 m. [2][3][8][7]

Description

The shells of Turbinella angulata can reach a size of 12.7–49.6 centimetres (5.0–19.5 in).[3][8][6] These large shells are heavy and fusiform, with a sculpture of 8 to 10 prominent ribs angled at shoulder. Columella shows three strong folds. The basic colour of the external shell surface is white, while the inner are may be pink or orange.[7]
