While out on a morning walk on a popular running trail in Charlotte, North Carolina on Monday, Jessica Jackson spotted something unusual in the shrubs beside her.

When she took a closer look, she spotted a large ball of snakes, all different kinds, sizes and colors.

Jackson took a picture, which went viral on the social media, after it was shared by a local resident. It was an unusual sight, but joggers say snake sightings are frequent in the area.

Jogger Bryan Neil said he came across one the same morning.

“Right under the tunnel is a black snake probably about three or four feet long that scared the crap out of me,” Neil said.

A “ball of snakes” may seem terrifying, but it is actually not that rare of an occurrence, especially in the spring.

“Snakes are coming out of hibernation and they’re beginning to mate,” said David Crowe of Critter Control in Charlotte. “So they’re sunning in very obvious places.”

When males catch the pheromone scent of a female, they will swarm over her, forming a “mating ball,” a Science report explains.

The male snakes then engage in a non-violent combat, by placing their chins on the top of the other males’ heads and pushing down in order to win the mate.

After mating, the female may store the sperm for over a year, and then it will choose, which male’s sperm she wants to use to fertilize her eggs.

While the “ball of snakes may surprise runners, they do not pose much of a threat.

There are 37 snake species native to North Carolina, in which 6 are venomous: the copperhead, cottonmouth, pigmy rattler, canebrake, diamondback and coral snake.
