Charonia
Triton's trumpet
Triton's trumpet (Charonia tritonis) is the half-metre spiral shell blown as a horn across the Pacific and one of the largest gastropods; Charonia lampas is the Mediterranean and Atlantic relative. Because the animal is a key reef predator, it is protected in much of its range, and Stratum flags Charonia for the compliance gate. Old collection shells are legal to hold but should be sold with provenance.

CITES and protection
Not CITES-listed, but Charonia tritonis is protected in Australia, Fiji, India, Indonesia, Seychelles and other range states because it controls crown-of-thorns starfish; Charonia lampas is protected in parts of the Mediterranean. Shells offered without provenance may be illegally taken.
Care (Byne's disease)
Triton shells are large and stable; older painted or varnished souvenir shells should be described as such.
