about spiny lobster
The spiny lobster makes a remarkable annual migration in which large numbers of lobster move single file across the sea floor from shallow to deep water. Although the purpose of the migration is poorly understood, it is believed to be involved with reproduction and occurs just before spawning season. When spring comes, the adult females spawn thousand of eggs in the deep sea waters.
The lobster begins its life as a tiny, floating larva, a component of plankton and remains at the mercy of marine currents for about one year before becoming a small lobster. With the sea movement, the lobster returns to the coast to live protected by rocks and vegetation.
Spiny lobster must shed their exoskeleton to grow, by a process called molting (just like a snake has to shed its skin.) Spiny lobster molt several times a year as juveniles, once a year as adults. The lobster splits the old shell in half where the main body meets the tail, and crawls out, leaving behind the molted shell in such perfect condition it can easily be mistaken for a live animal.The lobster eat their old shell. Lobster continue to grow throughout their lives which can be about 8 to 10 years.
Lobster, common name for marine decapod (five pair of appendages on the thorax) crustaceans. Lobster are invertebrates, animals without a backbone.This crustacean has a hard exoskeleton, 5 pair of jointed walking legs, a segmented body, sensory antennae, a tail fan, and compound eyes on stalks. The tail is segmented and can be rapidly curled under the body to propel the lobster backward. Lobsters are cold-blooded; their body temperature depends on the temperature of the water.
