The lobster is a large crustacean that lives in the sea and is often seen swimming in the ocean’s shallow waters. Its long body and muscular tail make it easy for it to hide in crevices or burrows on the sea floor and find food, shelter and safety from predators. Lobsters are also able to travel far distances and are known for their ability to move through water.

The body of the lobster has six segments that are not fused together to allow flexibility and movement. The flexible abdomen is used to defend the lobster’s territory and for hunting. The lobster can contract its abdomen forcefully and retract it quickly to escape danger.

Its antennae are a vital tool for the lobster to detect prey that is far away. The antennae can pick up odors and chemical signals that are carried by the ocean water, and these help a lobster to find its food, choose a mate and decide whether or not it is in danger.

Lobsters are nocturnal hunters and can find their way into the deep sea by using their antennae to spot prey. They are able to use these antennae in the dark and they can move through the murky water without being spotted by other animals.

Unlike other crustaceans, lobsters are able to regenerate their claws and walking legs when they break them. This is called reflex amputation and is a very important ability for the lobster to have.

Another interesting fact about lobsters is that they can molt their shells as many as 20 to 30 times before they reach market size (a pound). This process allows them to replenish the calcium they lose in their old shell and it helps to strengthen the new one that forms.

When a lobster is molting, it will usually eat parts of its old shell to replenish the calcium. It will then regrow the shell in about 14-30 days.

The body of the lobster is composed of a large carapace and a smaller thorax. The thorax has a number of compartments, including two large stomachs that are found at the front and back of the shell. The stomachs are made of fat which acts as insulation to protect the lobster from predators.

Its eyes are located at the front of the head. They are used to hunt for small animals and insects, as well as frogs and other small fish.

They have five pairs of legs and their first pair has pincers, which are sharp, small, scissor-like claws. The inside of the pincers has tiny hairs that are sensitive to touch and taste.

There are more than 400 different receptors on these antennules that can be used to detect a wide range of odors and chemicals, making it possible for a lobster to identify its prey even if it is far away.

The legs and feet of the lobster are also used in nocturnal hunting. Their chemoreceptors are very sensitive and can pick up a wide range of odors and chemical signals from prey, including frogs, mussels and fish.
