Distribution

This species is endemic to the eastern coast of the United States, from Cape Cod, Massachusetts to northern Florida. It has also been introduced into San Francisco Bay.

Shell description

Shells of the channeled whelk typically reach 5 to 8 inches in length. The shell is smooth and subpyriform (generally pear-shaped), with a large body whorl and a straight siphonal canal. Between the whorls there is a wide, deep channel at the suture, and there are often weak knobs at the shoulders of the whorls. Finely sculpted lines begin at the siphonal canal and revolve around the shell surface.

The color of the shell is typically a buff gray to light tan. The shell aperture is located on the right side, i.e. the shell of this species is almost always dextral in coiling. Left-handed or sinistral specimens occur rarely.

Channeled whelks prefer sandy, shallow, intertidal or subtidal areas, and can be common in these habitats. They tend to be nocturnal and are known to eat clams.

One of their predators is the blue crab Callinectes sapidus . [2]

Human uses

The species is edible.

Busycotypus canaliculatus, along with hard clam, is used in the creation of wampum, which is a traditional shell bead made by the Eastern Woodlands tribes of Native Americans. White wampum beads are made of the inner spiral or columella of the channeled whelk shell Busycotypus canaliculatus or Busycotypus carica. Sewant or suckauhock beads are the black or purple shell beads made from the hard clam. Before European contact, strings of wampum were used for storytelling, ceremonial gifts, and recording important treaties and historical events, such as the Two Row Wampum Treaty and Hiawatha belts. Wampum was also used by the northeastern Indigenous tribes as a means of exchange, strung together in lengths for convenience. [3]

Whelks are any of several carnivorous sea snail species with a swirling, tapered shell. Many are eaten by humans, such as the common whelk of the North Atlantic. Most whelks belong to the family Buccinidae and are known as "true whelks." Others, such as the dog whelk, belong to several sea snail families that are not closely related.
