Busycotypus canaliculatus

Busycotypus canaliculatus, commonly known as the Channeled Whelk or the Knobbed Whelk, is a species of large sea snail, a marine gastropod mollusk in the family Busyconidae, the busycon whelks.

Description

The shell of Busycotypus canaliculatus can reach a length of approximately 30 cm. The shell has a high conical shape, it is sturdy and has a large body whorl. The surface is smooth and shiny, with a cream color and brown bands. The aperture is large and oval, with a siphonal canal. The operculum is horny and oval.

Distribution and habitat

Busycotypus canaliculatus is native to the Atlantic Ocean, specifically the western Atlantic from Cape Cod to Northern Florida. It is commonly found in shallow waters, on sandy or muddy bottoms.

Life cycle and behavior

The Channeled Whelk is a carnivore, feeding mainly on bivalves. It uses its long siphon to locate its prey, then uses its strong foot to hold the bivalve steady while it drills a hole in the shell using its radula. Once the hole is drilled, it injects digestive enzymes and consumes the liquefied tissue.

The species is gonochoristic, meaning individuals are either male or female. The female lays egg cases which are often found washed up on beaches, sometimes referred to as "mermaid's necklaces".

Human interaction

The Channeled Whelk is commercially harvested, particularly in the Mid-Atlantic region, for its meat, which is used in seafood dishes.
