How the Everglades crayfish lives

In the rainy summer and fall, it lives along flooded shores. It catches tadpoles, small fish and insects, and also eats aquatic plants. It lays eggs inside its burrow during the dry season. When the shore floods again, it comes to the surface with its young still attached to its body.
