The world's largest snake cave awakens after hibernation

After a long hibernation, more than 750,000 red striped snake snakes emerged from underground caves in Narcisse, Canada town to search for partners.

Similar to other snakes, red striped snakes are cold-blooded animals.In winter, when temperatures drop below 0 degrees C, they hibernate for 8 months.(Photo: National Geographic).

Manitoba, Canada, is home to many sinkholes on limestone floors in the topsoil.These underground caves become the ideal place for snakes to experience 8-month hibernation.(Photo: National Geographic).

However, the cave is quite narrow.Thousands of snakes crawling in the cave are only as big as a living room.(Photo: Reuters).

When the spring comes, the solid red striped harness crawls up to crawl out of the cave, forming a solid solid carpet.(Photo: Government of Manitoba).

This is the peak time of mating season.Males eagerly look for females to mate in areas around the cave.(Photo: New York Times).

The ratio of sex difference makes male snake crawling out of the nest first and waiting for the snake to gradually appear in the next few weeks.(Photo: Government of Manitoba).

When seduced by pheromones secreted by females, some male snakes will rub their chin along the female's back.This phenomenon is called "mating ball" so that many male snakes want to mate with a female snake.(Photo: New York Times).

The male snake closest to the female will mate with it, leaving a mucus inside the female body.This mucus blocks off the female reproductive tract for about two days, forcing other males to stay away.(Photo: Robert Mason & Christopher Friesen / University of Oregon).

After that, female snakes can crawl out of the cave to feed and give birth in the summer.Each time it can lay 40-50 eggs.(Photo: Robert Mason & Christopher Friesen / University of Oregon).

If the female refuses to mate, it can prevent male snake sperm from fertilizing its eggs with a mysterious "contraceptive" mechanism.The female can wait for the mucus to dissipate and pair with another male snake.(Photo: New York Times).

In September, the snakes returned to the cave to prepare for the winter and continued to spend 8 months hibernating.(Photo: New York Times).
