![]() ![]() The anatomy of the lobster includes the cephalothorax which is the head fused with the thorax, both of which are covered by the carapace, of chitinous composition, and the abdomen. A freshly caught lobster will have a claw which is full and fleshy, not atrophied. According to the Guinness World Records, the largest lobster was caught in Nova Scotia, Canada, and weighed 20.15 kg (44.4 lb).Īlthough clawed lobsters, like most other arthropods, are largely bilaterally symmetrical, they often possess unequal, specialized claws, like the king crab. In fact, lobsters may exhibit "negligible senescence", in that they can effectively live indefinitely, barring injury, disease, capture, etc. Although lobster skin has been found in the stomachs of lobsters, this is because lobsters will eat their shed skin after molting.Lobsters grow throughout their lives and it is not unusual for a lobster to live for more than 100 years.One such 100 year old lobster was donated to the Huntsman Marine Science Center in St. Occasionally, they will scavenge if necessary, and may resort to cannibalism in captivity however, this has not been observed in the wild. Lobsters typically eat live food, consisting of fish, mollusks, other crustaceans, worms, and some plant life. ![]() ![]() They do however, exhibit three remarkable evolutionary advances that have led to their great success: an exoskeleton: a strong, lightweight, form-fitted external covering and support, striated muscle: a quick, strong, lightweight form of muscle that makes rapid movement and flight possible, and articulation: the ability to bend appendeges at specific points. Lobsters have 10 legs, with the front ones adapted to claws.Īs arthropods, lobsters have not achieved the nervous system development of cepholopod molluscs, nor do they have the advantages of extraordinary eyesight. During the molting process, several species may experience a change in color. Like most arthropods, lobsters must molt in order to grow, leaving them vulnerable during this time. They are invertebrates, with a hard protective exoskeleton. They generally live singly in crevices or in burrows under rocks. ![]() They live on rocky, sandy, or muddy bottoms from the shoreline to beyond the edge of the continental shelf. Lobsters are found in all the oceans of the world. ![]()
