Like most arthropods must molt lobster to grow, making them vulnerable. Lobsters have 10 walking legs, the front three pairs bear claws, of which the first are larger than the other. Although, like most other arthropods, lobsters are largely bilaterally symmetrical some genera possess unequal, specialized claws.  Lobster anatomy includes the cephalothorax which fuses the head and chest, covered by a shell of chitin, and abdomen. Because lobsters live in a murky environment at the bottom of the ocean, they mostly use their antennae as sensors. The lobster eye structure prior a convex reflecting retina.

Lobsters possess a green hepatopancreas, called tomalley of chefs, which functions as the animal liver and pancreas.

It has been argued that lobsters can have negligible senescence and some scientists have argued, could actually live indefinitely, apart from injury, disease, capture, etc. According to Guinness World Records, the largest lobster was in Nova Scotia, Canada caught and weighed 20.15 kg (44.4 lb). Lobsters are found in all oceans.

Lobsters are omnivorous and usually eat live prey such as fish, molluscs, crustaceans, worms and some vegetables. Although lobster skin has been found in the stomachs of lobsters, it's because lobsters eat their shed skin after molting In general, lobsters 25-50 centimeters (10-20 inches) long, and move. Animal parasites of the genus Symbion, the only member of the tribe Cycliophora live exclusively on lobster gills and mouthparts. Different types of Symbion were found in the three commercially important North Atlantic lobster Nephrops norvegicus, Homarus americanus and Homarus gammarus.

Lobsters can. Lobster is in water from 1 to 500 fathoms fished (900 m 2), although some lobsters live in 2,000 fathoms (3,700 m). A lobster fisherman can lay up to 2,000 traps. Around 2000, expanding aquaculture due to overfishing and high demand, lobster. Since 2008, no lobster aquaculture operation had achieved commercial success, mainly due to the fact that lobsters eat each other (cannibalism) and the slow growth of the species, these two problems it is difficult to make profitable lobster aquaculture
