Notostraca Branchiopoda Crustacea Arthropoda

Notostracans are tadpole shrimps, of which only 10 species are known worldwide. They inhabit quiet, fishless, usually temporary, freshwaters where they crawl over the bottom or swim in the water. They have a carapace and the trunk is composed of about 40 segments and is divided into a large thorax and a small abdomen.
