Winter numbness of the lower animals

Numbness animals with cold blood starts in the fall, as cool their blood. When it's cold, the animal seems to be completely dead. I can not believe that it remains at least a spark of life. The eye can not distinguish it numb creature from dead body. Freeze the muscles and nerves, intestines stop working, almost stopped breathing and circulation. But it is not death. This time, though, and almost full, stop living. The organism is alive, he again begins to move when it's necessary conditions for all life, ie heat. Only thanks to this property all land animals with cold blood going through the winter. In some species of adult animals survive, while others - the larvae or pupae, the third - the pending fall of the testicles. Hardy to cold the animals before proceeding to stupor, still take steps to protect themselves from too sharp frost. Spiders hiding under moss, in bark cracks, under opavshuyu foliage, climb into the depths of anthills (weakened from the cold ants admit it).
