Ostracoda

Caption

Mussel shrimps (Ostracoda) are small, bivalved crustaceans living in marine and freshwater environments. Their calcified carapace is readily fossilized, resulting in a fossil record stretching back almost 500 million years. This green freshwater species Eucypris virens prefers temporary pools (left in lateral view, right in ventral view, total body length approx. 1.8 mm).
