The feeding methods of gastropods and bivalves.

The feeding methods of gastropods:

They feed on from the rock surface. They feed on seaweeds, animals that are static. They use a hard plate that is present in the teeth called radula for feeding. They are not filter feeding organisms.

The feeding methods of bivalves:

They feed form the water. They feed on phytoplankton that are seen in water. They feed on the smaller things that pass through their grills. These are filter feeding organisms.
