Giant isopods living in a Japanese aquarium, not eating for five years

Caught in the Gulf of Mexico, the representative of crustaceans, which were brought to Japan in September 2007, reaching a length of 29 cm and weighs 1 kg. Feeding the last time this natural wonder of the oceanarium workers succeeded in 2009 - then isopods eaten with bones for five minutes a large horse mackerel. Since then, the staff attempts to feed the animal with a terrifying appearance were unsuccessful. "We try to do everything in our power, but it continues to remain indifferent to the feeding ground," - said one of the employees of the aquarium. However, such a long hunger strike does not prevent crustacean feel normal.

Science, little is known about isopods because they live in very deep water. The most common sites of their habitats are depressions Gulf of Mexico and Caribbean Sea. Researchers still find it difficult to explain the sudden failure of the arthropod food, and how he manages to still maintain vital functions. "Giant isopods, as a rule, are constantly in a state of near-hibernation - said Taeko Kimura, a marine ecologist at the University of Mie. - Proper hunger animals recognize bad, so the amount of energy consumed by respiration and other vital activities deliberately cut. "

Many isopods, as suggested by Kimura may have accumulated in the liver fat layer, a gradual flow which helps them to maintain vital functions of the body, even without food consumption. Only now, four years - this is an outstanding time. The version of the self-generation of isopods living organisms such as plankton and algae, which he then quietly eats, is also excluded - arthropod lives in a tank with artificial sea water, under the close supervision of experts.

In the town of Toba, in the same aquarium lived for a long time, another giant isopods, who died of natural causes a few years ago. Taking into account the fact that it differed quite a healthy appetite, aquarium workers and experts can not explain the buoyant state of "hunger strike" isopod, who lives in an aquarium at the moment.
