1. SEA SNAILS
Sea snails are not different from the land snails and the freshwater snails since they are also shelled gastropods. They can also be called Marine snails or Prosobranchs. The sea snails are known for their soft, flexible body and their conical or spiral shells. The sea snails have thousands of species with varying feeds. Few of the sea snails are carnivorous and feed on smaller marine animals while more than half of the sea snails feed on algae, corals, plankton, and flora traces. There are various means of respiration for different species of sea snails; some breath through their gills while others inhale oxygen through their primitive lungs.

The land snails have a soft body which is more obvious than that of the marine snails. Most of the species of the land snails breathe through their lungs while few of them breathe through their gills. Even though they are regarded as terrestrial snails they do depend on moisture to survive. They secrete mucus which functions in lubricating their body and permits easy locomotion through any surface, either rough or smooth. Another characteristic of the land snail is that they have small tentacles on their heads and a primitive brain is not also excluded.
