+ Lobster, Biology: Decapods :: Seafood
  * Lobsters are invertebrates. This process of shedding is called 'moulting'. Some lobster species' colors change when they are moulting.
  * But lobsters who have claws often have claws of different sizes, for example the king crab. These unequal claws are for special actions. When a fisherman catches a lobster, the lobster's claw is often full and fleshy, not small. Lobsters have a cephalothorax which is the place where their head connects to the thorax. The carapace covers the cephalothorax and the thorax. The carapace is made of chitin. A lobster's head has two pairs of antennae and three pairs of jaws. Lobsters use their antennae to feel where they are. They cannot see very well.

Lobsters use their antennae to feel where they are. They cannot see very well. The abdomen of the lobster includes legs and a tail fan.
  * Lobsters usually move slowly by walking on the bottom of the sea floor. However, when they are in danger and need to escape, they swim backwards quickly by curling and uncurling their abdomen. Lobsters can move at a speed of 5 metres per second.
  * Decapod's are an order of crustaceans in the class Malacostraca. Many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp are in this order. Crabs are mixed feeders, taking algae and  shellfish such as molluscs. Lobsters eat mostly live prey.
