THE CRAYFISH, (Astacus fluviatilis,)
May be called the lobster of fresh water, and its presence is generally esteemed an evidence of the goodness of the water. Crayfish are considered a very strengthening food. They are caught in shallow brooks, hid under large stones, out of which they crawl backwards to seek for their prey, which consists of small insects; the hooks employed to catch them are baited with liver or flesh, which they nibble most greedily.
THE CRAB. (Cancer pagurus.)
Crabs are of various sizes, some weighing several pounds, and others only a few grains, all of different species. They do not move forward, but sideways. They have a small tail closed on the body; which forms a considerable and essential difference between them and the lobsters, prawns, shrimps, and crayfish.
