From the fossil record, it is known that modern branchiopods date back to the Early Devonian, by which time they were fully adapted to freshwater habitats ( 22 ).Clam shrimps and water fleas usually range in size from 0.008 to 0.7 inches (0.2 to 17 millimeters). They resemble clams and other bivalve mollusks that have hinged shells. These branchiopods are flattened from side to side and are protected by a large, hinged or folded carapace that mostly or completely covers their bodies and limbs.For these reasons, the use of large branchiopods in monitoring temporary ponds is highly recommended (Waterkeyn et al., 2011).
