Although many people know of lobsters, not too many people know much about them, except mainly that they serve as a very good meal for many of us. They have long bodies with muscular tails, and live in crevices or burrows (not boroughs) on the sea floor. Out of the five pairs of legs that they have, three of them have claws, which include the large pair in the from of the body that are much bigger than the others.
Bone Structure
In order for lobsters to grow, they must molt, which is a form of shedding that leaves them very vulnerable at times. Lobsters in total have ten legs, the first six being claws. The head and thorax of a lobster is fused by the cephalothorax, and both the head and the thorax are covered by a chitinous carapace. The abdomen is the third part of the body, where the tail is located. Because lobsters live in murky environments under the sea, they use their antennae as sensors. The main duty of a lobster's exoskeleton is protection. It protects the lobster from predators and possible injuries, as well as acting as the framework to connect the organs together.
