Description

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]

Distribution

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]

Lobatus Gigas Media

  • For a number of years during the 20th century, this very early illustration was designated as the neotype of this species: a figure of A. gigas from Recreatio mentis, et occuli (1684). The shell in the figure appears left-right reversed because of the engraving process. The original type was subsequently found, invalidating this designation.

  • Five different views of an adult shell of A. gigas: abapertural (upper left), lateral (center), apertural (upper right), apical (lower left) and basal (lower right). Note: The lip of this shell has been filed down or cut down artificially, a common practice in the shell trade.

  • An adult queen conch shell with the lip completely intact

  • Abapertural (left) and apertural (right) views of a beachworn and slightly bleached-out juvenile shell of A. gigas

  • Aliger gigas fossil from the Pleistocene (Eemian) of Great Inagua, the Bahamas.

  • Adult shell, apical view, Gualtieri, 1742

  • Adult shell, ventral view, Gualtieri, 1742

  • Adult shell, dorsal view, Gualtieri, 1742

  • Juvenile shell, Tryon, 1885

  • The foot (with a brown, sickle-shaped operculum), eyestalks and snout of Aliger gigas exposed through the shell's aperture. At the tip of each eyestalk there is a well-developed eye. Near the tip is a small sensory tentacle.
