Charonia
Charonia is a genus of very large sea snail, commonly known as Triton's trumpet or Triton snail. They are marine gastropod mollusks in the monotypic family Charoniidae.[1][2]
The common name "Triton's trumpet" is derived from the Greek god Triton, who was the son of Poseidon, god of the sea. The god Triton is often portrayed blowing a large seashell horn similar to this species.
This genus is known in the fossil records as far back as the Cretaceous period. Fossils are found in the marine strata throughout the world.[3]
Species within the genus Charonia have large fusiform shells, usually whiteish with brown or yellow markings.
The shell of the giant triton Charonia tritonis (Linnaeus, 1758), which lives in the Indo-Pacific, can grow to over half a metre (20 inches) in length.
One slightly smaller (shell size 100–385 millimetres (3.9–15.2 in) but still very large species, Charonia variegata (Lamarck, 1816), lives in the western Atlantic, from North Carolina to Brazil.[4]
