Shell Identification

The shells below are all Univalves:

These creatures, which are also known as gastropods, have a single, shell that is usually coiled.  They have a distinct head with tentacles and a rasping tongue (radula).  Most of the 105,000 known species in this group have shells.  Half of the species are marine while the remainder is either terrestrial or fresh water.  The sexes are separate in most marine species.  Free-swimming larva emerges from eggs laid into the water.   This larva eventually grows into a shell adult.  The average life expectancy of a gastropod is five years while some have survived to 30 years.  They may be carnivorous, herbivorous or parasitic.

Bivalves
Also known as pelecypods, they are mollusks with two valves joined by a hinge.  Most of the 20,000 species are marine including clams, mussels, oysters and scallops.  About one third of the species live in fresh water.  They lack a head and radial teeth.  They feed on microscopic plant life aided by their gills.  The tow shells (valves) are kept closed by strong muscles.  The sexes may be combined in one individual or may be separate.  Most lay their eggs directly into the water.  Oysters, clams, and scallops are a major source of food.
