|A shell of a channeled whelk|
The channeled whelk, Busycotypus canaliculatus, previously known as Busycon canaliculatum, is a very large predatory sea snail, a marine prosobranch gastropod, a busycon whelk, belonging to the family Buccinidae. 
This species is edible.
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.
