LOBSTER

The lobster is often confused with the crayfish. Clawed Lobsters have larger claws than crayfish..

Clawed lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. Lobsters are economically important as seafood, forming the basis of a global industry that nets more than US$1 billion annually.

Though several groups of crustaceans are known as "lobsters," the clawed lobsters are most often associated with the name. They are also revered for their flavor and texture. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws (chelae), or squat lobsters. The closest relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish.

Recent research has led scientists to believe that lobsters may be one of a small number of species which do not die of aging. Lobsters do not slow down, weaken, or lose fertility with age. In fact, older lobsters are more fertile than younger lobsters. The reason for this infinite longevity is said to be due to telomerase, an enzyme that repairs DNA sequences of the form "TTAGGG". This sequence is often referred to as the telomeres of the DNA. In fact, lobsters may exhibit negligible senescence, in that they effectively live indefinitely, barring injury, disease, capture, etc.[12] They can thus reach impressive sizes. According to the Guinness World Records, the largest lobster was caught in Nova Scotia, Canada, and weighed 20.15 kilograms (44.4 lb)

Lobsters are found in all oceans. They live on rocky, sandy, or muddy bottoms from the shoreline to beyond the edge of the continental shelf. They generally live singly in crevices or in burrows under rocks.

They are invertebrates, with a hard protective exoskeleton. Like most arthropods, lobsters must molt in order to grow, which leaves them vulnerable. During the molting process, several species change color. Lobsters have 10 walking legs; the front two adapted to claws.

As arthropods, lobsters have not developed the nervous system of cephalopod mollusks, nor do they have the advantages of good eyesight. They do, however, exhibit three remarkable evolutionary advances that have led to their great success. Their exoskeleton is a strong, lightweight, form-fitted external covering and support. They possess striated muscle: quick, strong, and lightweight, it enables rapid movement. Finally, articulated appendages allow their limbs to bend at specific points.

Lobsters are omnivores, and typically eat live prey such as fish, mollusks, other crustaceans, worms, and some plant life. They scavenge if necessary, and may resort to cannibalism in captivity; however, this has not been observed in the wild. Although lobster skin has been found in lobster stomachs, this is because lobsters eat their shed skin after molting
