Origin
Lobsters are part of the family Homaridae, a family of marine crustaceans. From an economic point of view lobsters are the basis of a global industry. They fish for consumption and for that the whole business costs amount to more than a billion dollars annually.
They are revered for their flavor.
They are found in all oceans. they live on sand, mud or rocky bottoms of waters. They generally live alone in burrows or in rocks.
The European lobster found in Britain and Ireland is smaller, more expensive and rarer than that found in America.
Lobster Feed
Lobsters are omnivorous and eat live food. They feed on fish, mollusks, other crustaceans, worms and some plants.
They also eat leashes and resort to cannibalism in captivity if needed, this has not been observed in the wild.
After moulting it eats its "skin".
Lobster Appearance
Lobsters are marine invertebrate animals that have a protective Bony carapace. Like most lobsters, they shed. During the moulting process they change color.
They have 10 legs to move with and two pliers like two claws for cutting. It has two long antennas that use them as sensors when walking on the bottom of the water because it disturbs the water and the eyes cannot help it in these conditions.
Lobsters, like snails andpaianjeni have blue blood due to a substance that contains copper. Lobsters have a liveropancreas that replace the liver and pancreas.
Generally lobsters are 25-50cm long. When they run they swim fast backwards at a speed of 5m/s.
Lobster Behavior
Research shows that lobsters cannot slow down, weaken or lose fertility with age. The older lobsters grow, the more fertile they are.
This is due to an enzyme and its DNA. Because of this, lobsters can reach incredible sizes, in Canada was caught a lobster weighing over 20 kg.
The most common way to kill a lobster is by scalding it with boiling water, but it is also practiced the method of sticking a knife into the brain before boiling. In some countries it is forbidden to kill by boiling, for example in Italy offenders receive fines of 500 euros.
lobsters are caught in cages placed in water with depths between 2 and 900m, although lobsters are also found at 3700m. steel cages are covered with plastic or wood. A lobster fisherman can lay out 2,000 traps.
Lobster Breeding
Male lobsters deposit sperm on the underside of the female, and she will later use the sperm. The female can store sperm for several months until it is time to lay eggs, usually between July and august.
Females give birth every two years. The number of eggs depends on the size of the female, about 5000 eggs for a 25cm female and 40,000 for a 36cm female.
There were also cases when a 43cm female laid 63,000 eggs and another larger one almost 100,000.
The egg mass is permanently" aerated " so as not to deposit impurities and not to cover to be well oxygenated. Female lobsters carry their eggs for 10-11 months. After birth the young are small and vulnerable (2-3cm long).
The high mortality in infancy is why the female lobster lays so many eggs.
