July Thirty-first
The river crab, or crawfish, has five pairs of walking legs and six pairs of swimming legs. If a leg is lost, another will grow within a year. The female lays a large number of eggs, which are attached to the fringes of her body. These crabs have two pairs of antenna-like organs, one to feel with and the other for hearing. The compound eyes are set on two pegs that can be protruded or depressed at will.
