ocr: crustaceans Crustaceans like this spiny lobster are animals which spend all of their lives on the ocean bottom. They have segmented bodies and a huge pair of pincers which they use for feeding and defense. Lobsters have four pairs of walking legs and several pairs of modified legs which they use for swimming. They carry their eggs on the swimming legs, and the lobster eggs hatch into larvae which swim off and later develop into hard-shelled crustaceans themselves,
