About seed shrimp:
Seed shrimp are small crustaceans about one mm in size. They are called "seed shrimp" because they resemble a shrimp inside a seed pod. Their shell (the carapace) is hinged like a clam and held shut with adductor muscles. The head (cephalon) has five pairs of hairy legs. The pronged tail is called a furca. They live in most water environments, both marine and freshwater. Ostracods reproduce sexually and asexually.
