Facts about Lobsters, "Scientific name for Lobster is Nephropidae". A lobster is a big marine crustacean that comes from the Nephropidae family. Lobsters are highly valued as seafood, and they are economically significant, and are regularly one among the most lucrative commodities in coastal regions they inhabit. They are commercially important species among which the most important species include the Homarus genus from the northern parts of Atlantic Ocean, the genus Nephrops from the Northern-hemisphere and the Metanephrops genus from the Southern Hemisphere. Even though some other groups of crustaceans have the utterance lobster in their names, the incompetent term lobster usually refers to the lobsters with claws of the Nephropidae family.
Features about Lobsters
Generally, lobsters can grow to a maximum size, ranging from 10 inches to 20 inches (25 cm to 50 cm), and they move by gradually walking on the sea ground. They have long bodies with muscular tails, and live in crevices or burrows on the sea floor.
They are the invertebrates with a hard defending exoskeleton, and they must molt so as to grow, which leaves them susceptible. During the process of molting, they undergo a change in their body color. These marine crustaceans have 10 walking legs, among which the front three pairs have claws, the first of which are bigger than the others. Even though lobsters are mostly bilaterally proportioned, some genera have uneven, specialized claws.
The structure of Lobster comprises the cephalothorax that fuses the thorax and the head, both of which are enclosed by a chitinous carapace, and the stomach. The head of the lobster bears antennules, antennae, mandibles, the first, second, and third maxillipeds and the first and second maxillae. As lobsters inhabit a gloomy environment at the ocean bottom, they typically exploit their antennae as detectors. The eye of the lobster has a reflective arrangement above a curved retina. On the contrary, nearly all complex eyes exploit a concave retina and refractive ray lenses. Their abdomen comprises swimmerets and their tail is made up of the telson and uropods.
Similar to spiders and snails, lobsters have blue blood because of the availability of haemocyanin that contains copper. They have a green hepatopancreas, known as the tomalley by chefs, which acts as the pancreas and liver of the animal. Generally, lobsters vary from other freshwater varieties in lacking the joint between the final two fragments of the thorax, and having full claws on the initial three pairs of legs, rather than a single one.
Diet for Lobster
Lobsters are omnivorous animals, and they usually feed on mollusks, fish, other crustaceans, young insects, and a few plant life.
Behavior of a Lobster
Generally, lobsters may not decelerate, deteriorate, or misplace fertility with their age, and that adult lobsters may be more productive than younger lobsters. This endurance may be attributable to telomerase, which is an enzyme that fixes long cyclic sections of DNA chains at the ends of chromosomes, called telomeres. Telomerase is articulated by lobsters during embryonic phases, but it is normally absent from mature stages of life. However, lobsters articulate telomerase as matures in the course of most tissues, which has been considered to be associated with their longevity.
The maximum lifespan of lobsters is 60 years.
