The Life of Animals | Lobster | Lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, lobsters must molt in order to grow, the which leaves Them Vulnerable. Although, like most other arthropods, lobsters are largely bilaterally symmetrical, They Often possess unequal, specialized claws, like the king crab. The lobster's head bears the antennae, antennules, mandibles, the first and second maxillae, and the first, second, and third maxillipeds. Because lobsters live in a murky environment at the bottom of the ocean, They Mostly Their use antennae as sensors. The lobster eye has a reflective structure above a convex retina.



Lobsters, like snails and spiders, have blue blood due to the presence of haemocyanin the which contains copper (in contrast, vertebrates and many other animals have red blood from iron-rich hemoglobin). Lobsters possess a green hepatopancreas, Called the tomalley by chefs, the which functions as the animal's liver and pancreas. In general, lobsters are 25-50 centimetres (10-20 in) long, and move by SLOWLY walking on the sea floor. Lobsters are found in all Oceans.

Lobsters are omnivores and eat live prey typically Such as fish, mollusks, other crustaceans, worms, and some plant life. Although lobster skin has been found in lobster stomachs, this is Because lobsters eat Their shed skins after molting. Lobsters may also be killed or rendered insensate IMMEDIATELY before boiling through a stab into the brain, in the belief That Will this stop Suffering.

Lobster is fished in water the between 1 and 500 fathoms (2 and 900 m), although some live lobsters at 2.000 fathoms (3.700 m).Agrowing niche lobster fisher may as many as 2.000 traps. Around the year 2000, due to overfishing and high demand, lobster aquaculture expanded. As of 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 make it Difficult to Make lobster aquaculture profitable.
