The species within this genus have very large shells, which can grow up to 30-35cm in length.

Charonia species are great predators, feeding mainly on other molluscs and starfish. Once it captures its prey, it grips it with its muscular foot, uses its radula or "tooth" to saw through its skin and injects a paralyzing saliva.
Triton's trumpets can be found all year round along the Istrian coasts at depths of up to 40m, mainly at night, when they are most active. It is possible to find three species of Triton Trumpets in the Istrian coasts: Charonia lampa, C. tritonis and C. variagata.
