Lobsters
Invertebrates are animals that do not have a backbone, and some groups have an external skeleton (exoskeleton) to support and protect the body. All groups of invertebrates have representatives in the marine environment (many of them are exclusively marine), which in these places are mostly benthic (they live on or buried at the bottom).
Crustaceans, such as lobsters and crabs, during growth shed the outer part of their exoskeleton in a process we call molting or ecdysis. All groups of invertebrates have representatives in the marine environment (many of them are exclusively marine), which in these places are mostly benthic (they live on or buried at the bottom). Spiny lobsters live in the tropical and subtropical waters of the western Atlantic, from North Carolina, USA, to Rio de Janeiro, Brazil, as well as the Gulf of Mexico and the entire Caribbean.
Caribbean spiny lobster - Panulirus laevicauda
A species of lobster from the Atlantic Ocean, found from the Caribbean Sea to southeastern Brazil. Lives in groups, up to a depth of 90 m. It is usually found in shallow water, hidden in crevices of rocks, eelgrass beds and corals. They are migratory animals, being able to carry out mass migration during the daytime, in which they form a line of up to 50 individuals, each animal having body contact with the next through the antennae. Females can go to deeper waters for spawning. They have nocturnal habits, eating during the night. They are primarily detritivores (they feed on organic remains), but they can also feed on other smaller crustaceans, molluscs, worms and even fish. They reach up to 45 cm in length.
