How does a conch look?

Conches are very pretty shells that usually appear in soft shades of cream, white, and/or pink. Most of the time, they are very large--as they are adapted to larger animal bodies, such as crabs--and found at the bottom of tropical bodies of water. At one end, a conch has a pointy formation that resembles a unicorn horn, and on the other it is smoother and rounder. On the bottom, there are two thick "lips" that form the gateway inside the shell.
