What does snake wrap mean?

Most snakes start to look for mates after stinging in spring. The skin of the female snake and the gland at the base of the tail can secrete a unique strong smell, which attracts the male snake to mate. When snakes hibernate, many snakes live together in groups, which can increase the chances of mating between male and female snakes after next spring. When mating, the male snake only uses one of two and a half penises. The male snake turns out one of the penis halves from the inside out through the cloacal hole, and the sperm is injected into the female snake's cloacal cavity along the shallow groove on the penis surface. In some kinds of snakes, sperm can survive in female snakes for 3-4 years, and they still have the ability to fertilize. When mating, the male snake and the female snake are twisted into a twist, and people who don't know think it is a fight. The female snake's connector is its anal cavity, which has no special structure, while the male snake's connector is a pair of bag-shaped half penises, which are located inside the caudal base. There are many small protrusions on the inner wall of the bag. The size, shape and number of thorns vary with the kind of snake, and the appearance of the half penis is also kind. When mating, the inside of the bag turns out and looks like a blooming flower. Half a penis is inserted into the anal cavity of the female snake for in vivo fertilization, but only one and a half penis is used for each mating. During the breeding season, a male snake can mate with several females, but females only mate once. Therefore, in snake farms, it is often a male snake and several female snakes pair up to breed. For example, it is enough to have two or three male snakes for every ten female snakes in the snake garden where silver ring snakes are cultivated. After mating, sperm can survive in the fallopian tubes of female snakes for a long time. For example, in the Snake Garden of Zhejiang Medical University in Hangzhou, a pair of vipers only mated once. After separation, the mother snake gave birth to three years of baby snakes, seven in the first year, 10 in the second year and 14 in the third year. Some snakes can live in females for five years once they mate. Agkistrodon halys are oviparous snakes, but most snakes are oviparous. Snakes usually have a nest every year.
