Lobsters are arthropods. Clawed lobsters compose a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. 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. Lobsters typically eat live food, consisting of fish, mollusks, other crustaceans, worms, and some plant life. According to the Guinness World Records, the largest lobster was caught in Nova Scotia, Canada, and weighed 20.15 kg (44.4 lb).
Lobsters molt, or shed their skin. Ecdysis is the molting of the cuticula in arthropods. Since the cuticula of these animals is also the skeletal support (the exoskeleton) of the body and is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvium.
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. The lobster’s head consists of antennae, antennules, mandibles, the first and second maxillae, and the first, second, and third maxillipeds.
Lobsters, like snails and spiders, have blue blood due to the presence of haemocyanin, which contains copper. In contrast, mammals and many other animals, have red blood due to the presence of haemoglobin, which contains iron. Inside lobsters is a green goopy substance called tomalley, which serves as the hepatopancreas, fulfilling the functions of both liver and pancreas.
Lobsters range in size from 25 cm to 50 cm long ( 10 to 20 inches ) and move slowly by walking on the bottom of the sea floor. However, when they flee, they swim backwards quickly by curling and uncurling their abdomen. A speed of five meters per second (about 11 mph) has been recorded.
