Knobbed Whelk!
 
 
Diet-  Knobbed Whelks eat clams. They eat using a radula, a rough tongue-like organ.

Anatomy-  The soft body is divided into the head, the visceral mass, and the foot. The Knobbed Whelk has two pairs of tentacles on the head, it has a light-sensitive eyespot located on each of the larger tentacles. The smaller pair of tentacles are used for smelling and touching.

Interesting Fact- The whelk builds the hard shell from calcium carbonate that it gets from the sea.
