Lobsters are part of the family of big crustaceans. They have long bodies with a very hard tail and they live in empty spaces of the sea floor but also on rocks. They have ten claws in total, including the bigger claws.

They walk very slowly but they swim backwards and very quickly. They are invertebrates and they have a very hard exoskeleton.

Lobsters normally go alone (they rarely interact with each other) and for hiding usually they use spaces under rocks. When they are in danger they usually swim very fast. When lobsters grow up they make their own houses, called carina that has a volcano shape.

When lobsters are little they are larvae and they do not have protection. It has to find a place where to grow and to produce the hard protection.

There is a social status between the lobsters, although they do not communicate pretty much and they do not like each other a lot. For example, a very well-known male lobster among its community will have a house and he could communicate with females. The lobsters become known because of their urine, so they can recognize each other. They communicate by pissing in each other's faces. They do this for flirting or for discussing when they are angry.

When lobsters are in groups, they coordinate pretty well. They can be hours walking in the same direction, and they do not have a leader. They go in groups for finding more food.
