Lobsters are crustaceans that are found in all oceans. They are typically bottom-dwelling animals and prefer to live in rocky areas where they can find shelter from predators. Lobsters have a hard exoskeleton that protects them from injury, and they have two powerful claws that they use for capturing prey and defending themselves. Lobsters are omnivores and will eat a variety of plants and animals, including fish, mollusks, crustaceans, and worms.
