MOSCOW, December 25. / TASS /. White-breasted hedgehogs in the Moscow Zoo went into hibernation. This was reported on Friday in the press service of the institution.
“Even during the first frosts, our white-breasted hedgehogs curled up into balls and fell asleep for the winter. Before that, they were actively preparing a place to sleep - hedgehogs sleep in deep burrows. if the hole freezes in winter, the hedgehog may die, "the message says.
According to the director of the Moscow Zoo Svetlana Akulova, hedgehogs actively ate all autumn in order to gain sufficient weight.
"The zoo staff carefully monitor this process. Before hibernation and in general throughout the year, hedgehogs are weighed to monitor their health," Akulova said.
During hibernation, life processes in hedgehogs greatly change: metabolism slows down, the body cools, the heart rate decreases from 180 to 20-60 beats per minute, they breathe only once a minute.
"Since the hedgehog lives in hibernation only at the expense of fat reserves, it loses up to 35% of its weight. Therefore, in order to winter well, the animal must weigh at least 600 grams in the fall. the same nest, "the message says.
