American Lobster

The lobster has a unique design. Its mouth is used for much more than just eating. If a lobster loses its claws and legs, it will use its mouth to pull itself around. The lobster does not chew its food; instead it has three grinders in its stomach that process the food. It uses its long antennae to feel the surrounding area, and its short antennules provide its sense of smell, which helps the lobster locate prey, predators, mates, and opponents. These designs all help the lobster survive.


  • The American lobster is normally a shade of reddish-brown.
  • Most people recognize the lobster by its two large front claws. These are two of their ten legs, but they are not used for walking. One claw is used to grasp something for a long time, and the other one is the pincher that is used to grab something quickly.
