4. Why have marsh birds such long beaks?
LESSON IV.
CRABS.
Little Crabs are to be found everywhere along the sea-shore--not the monsters of the fishmonger's shop, but small greenish-brownish Crabs. They live in the weed of the rock-pools, and in the wet sand. These are the Shore Crabs; the large Edible Crabs are a different kind, and live mostly in deep water.
Shore Crabs are quarrelsome little creatures; the larger ones are always ready to gobble up the smaller ones, or to snatch their food and run away with it. If you put some dead mussels or fish in a pool, you will be amused at their antics. How they scramble and fight! Crabs do not believe in "table manners."
