I'd always heard about the Triton's Trumpet (Charonia Tritonis) being one of the few predators to feed on the Crown of Thorns Starfish and I finally got to see one in action.
During the day, it seeks shelter in crevices and covers the opening with a lid. At night, it actively hunts, relying on its vision and sense of smell to locate prey. To capture its prey,
it extends its throat and shell beneath the body of the prey to flip it over. The struggle and consumption of the prey can last for up to three hours. The triton has been described
as tearing the starfish to pieces with its file-like radula.
