species of mollusc From Wikipedia, the free encyclopedia
Lobatus gigas, commonly known as the queen conch, is a species of large edible sea snail, as a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to 35.2 centimetres (13.9inches) in shell length.
The shell is characterized by its large size, solidity and sculptured design with large thorns. The mouth is large, calloused, has great lip colors white, pink, yellow and orange. Sifonales Channels, anal and notch estromboide are wide and well marked.[6][7][8]
Lobatus gigas is native to the tropical Western Atlantic coasts of North and Central America.[9][10][11] It lives in the greater Caribbean tropical zone.[10][12][13]
