Branchiopoda is a group of primitive and primarily fresh water crustaceans, mostly resembling shrimp. A few are well-known, including Artemia (brine shrimp, called Sea-Monkeys when marketed as novelties), and Daphnia, both of which are raised as aquarium food or as interesting pets in and of themselves.

In older classification, the superorder Diplostraca are made up of the two orders Conchostraca and Cladocera. Newer data suggests that these orders may be artificial (at least in their present state) as some of their members seem to have a paraphyletic origin within the Diplostraca. For the moment, the original classification system is still being used. Families not necessarily a complete list: Conchostraca is an Order in the Class Branchiopoda. ...

Even if a few species of water fleas have adapted to a life in the sea, these crustaceans primarily belongs in fresh water. This could mean they belongs to an old group who has become extinct in the rest of the aquatic hapitats of the world, or that they actually evolved and originated in fresh water from some ancient and long gone ancestor. The fact that they are specially adapted to temporary pools and/or waters that are too extreme for other animals to live in (like salt lakes), indicates that they could have searched refugee in these places because they weren't able to compete with or hide from more advanced groups of animals who they had to live side by side with elsewhere. These special habitats could offer a sanctuary for them they don't seem to have found anywhere else. This meant a short generation cycle and small body size. Most of them still can't live in waters where there are fish and other forms of advanced predators, as they are too slow and vulnerable to survive them. But some have evolved to cope with this problem well enough to survive and give life to future generations, even with predators around them. Their main defence is probably their high number thanks to their humble size, ability to produce many offspring and short cycle. While Leptodora, which are pretty big for Branchiopods, trusts on their very transparent body and diel vertical migration. They are so transparent that their shadow are said to be more visible than their body.
