Leptestheria dahalacensis

A clam shrimp that inhabits ephemeral and small permanent waterbodies in Eurasia. They are more closely related to water fleas than to bivalve clams. The animals react to danger by contracting the muscle, so that the valves of the shell close tightly and the crustacean, as if dead, lies motionlessly at the bottom of the pool.

As well as the enormous Lynceus, there were these smaller Clam Shrimp, from a different family, swimming about. There are 13 described species in the genus, and the family is found in seasonal wetlands, inland saline pools and lakes worldwide, with the exception of Antarctica where it gets a bit nippy.

Clam Shrimp (Orders Laevicaudata,Spinicaudata and Cyclestherida)

Clam shrimp are a group of unique bivalved branchiopods that have no relation to molluscan bivalves. Clam shrimp can be found worldwide, mostly in vernal pools and other small bodies of water, where the filter the water for passing nutrients and food. Like other branchiopods like the infamous Daphnia clam shrimp have several rows of legs which they use to swim trough the water. When threatened the clam shrimp like a true clam can close its hardy shell and will drift to the bottom until it is safe.
