The lobster is a type of marine crustacean that lives in burrows and crevices on the sea floor. It has long, muscular legs and a tail. Three of its five pairs of legs have claws, the first pair being larger than the others. It can grow up to 3 inches long, depending on the species.

Anatomy

The lobster’s skeletal system is quite complex. It is comprised of four articulated plates: the tergite (dorsal), the sternite (ventral), and the pleurites (lateral). Together, these four plates form a rigid arch, or exoskeleton. The tergites and pleurites are attached to the central telson, and the rear periods are mostly walking legs.

Life cycle

The lobster’s life cycle begins with its larval stage, where it floats near the surface of the ocean and feeds on plankton. The larval stage lasts four to six weeks, during which the female lays as many as 100,000 eggs. The larvae molt four times during this stage, changing appearance each time. After their fourth molt, the larvae sink to the ocean floor, where they seek shelter in cracks and crevices.

Communication

Lobsters communicate by squirting pheromones at one another. These chemicals act like hormones and are squirted into the other lobster’s face. The opposite lobster can then detect these chemical messages, and respond accordingly.

Traveling

When traveling with lobster, you must keep the animal in a moist, cool environment. If the lobster is not chilled, it could suffocate. Dry ice can freeze the shell, destroying the shape, flavour, and texture of the lobster. A cool pack or gel pack may help keep the lobster chilled, but you must never touch the lobster directly. To protect the lobster from the cold packs, place corrugated dividers between the pack and the lobster.

Cannibals

Cannibal lobster are not uncommon in captivity; lobsters can attack each other and eat each other. But in the wild, this is unprecedented. Noah Oppenheim, a graduate student at the University of Maine, was intrigued by the behavior and set up a camera trap with a juvenile lobster as bait. He found that as soon as the sun set, other lobsters would come in and begin eating the juvenile.

Conservation

The lobster fishery is a vital part of the North American economy. Many people in the North Shore are dependent on it. This industry was devastated when the Newfoundland cod fishery collapsed in the late 1980s, leaving thousands of people jobless. Since then, fishermen and scientists have been working to minimize the risk of another collapse. Having strict regulations on the fishing activity will help to ensure lobster survival and ensure that lobster stocks remain healthy.
