The incredible American lobster
Introduction
The American lobster (also known as Maine’s lobster) is a large -body claw lobster that supports a large and lucrative fishery throughout its distribution area. This species is closely related to the European lobster, but only distantly related to the thorny lobsters of the Caribbean and California, all of which are also commercially objective species.
Developing
The American lobster reaches a weight of at least 45 pounds (20 kg) and is the largest crustacean in weight in weight. Together with the true crabs, prawns and other lobsters, the American lobster is a decapod;It has ten legs and is covered by a thorny exoskeleton that gives it some protection against possible predators. Most American lobsters are oxidized brown, but fishermen and scientists have rarely observed a wide variety of strange patterns / patterns.
These include individuals that are bright blue, green, mottled and even some that are perfectly divided by half with different colors on each side (for example, half blue, half black, half black, half red, etc.). The front legs of the American lobster are modified in very large claws. The two claws are slightly different from each other, one is stronger and used to crush, while the other is more sharp and used to cut.
As in all decapods, the shell of the American lobster is really a skeleton on the outside of his body. The exoskeleton does not expand and, therefore, the lobster must regularly move it to grow. Before the mute, an individual begins to build a new and larger skeleton within the existing. As it becomes too large to be contained, it opens the outer layer and the new exoskeleton hardens.
During this process, the new exoskeleton may be soft for several hours and the lobster is very vulnerable to predation. During the day, American lobsters remain hidden throughout their rock reef habitats. During the twilight hours and at night, individuals are much more active and seek along the reef a variety of dams, including many types of invertebrates, decomposition organic matter and some algae.
These lobsters will eat most of the things they find. It is known that large fish and octopuses eat adult American lobsters, and a greater variety of fish eat youth. Unlike many aquatic species, American lobsters are reproduced by internal fertilization. After a male passes her sperm to a female, she stores the fertilized ovules on the ventral side of her body until they are born.
conclusion
American lobsters support a massive fishery in the northwest of the Atlantic Ocean, where several successful management regulations have been applied to ensure that the fishery will continue to be viable in the future. These include size limits, arts limits and other management techniques. Currently, populations seem to be stable and scientists do not believe that this species is at risk of extinction, but it is important to continue monitoring populations to ensure that the fishery remains viable and the species remains healthy.
