* Knobbed Whelk - Busycon carica
The knobbed whelk (Busycon carica) is a species of very large predatory sea snail, or in the US, a whelk, a marine gastropod mollusk in the family Busyconidae, the busycon whelks. It is found in shallow waters of the Atlantic Ocean off the east coast of North America from Massachusetts to northern Florida. The knobbed whelk is the second largest species of busycon whelk, ranging in size up to 30.5 cm. The shell of most knobbed whelks is dextral, meaning that it is right-handed. The surface is sculpted with fine striations and there is a ring of knob-like projections protruding from the widest part of the coil. The color is ivory or pale gray, and the large aperture (the inside of the opening) is orange. The canal inside is wide and the entrance can be closed by a horny oval operculum.

* Channelled Whelk - Busycotypus canaliculatus
The channeled whelk (Busycotypus canaliculatus) is a very large predatory sea snail, a marine prosobranch gastropod, a busycon whelk, belonging to the family Busyconidae. This species is endemic to the eastern coast of the United States, from Cape Cod, Massachusetts to northern Florida. The shell of the channeled whelk 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.
