Here's a disgusting sight you wish you have not seen.

A footage showing alien-like parasites bursting out of a dead cricket's body is going viral online. According to Science Alert, the parasites exploded out of the cricket after a hiker accidentally stepped on the insect.

"After I stepped on it it looked dead. Then a few seconds later Jarred's like what the? I did not know it, like, had shit crawling out of it," a guy said on the video.

The grossness did not end in the explosion part. Apparently after managing to free themselves from the dead cricket's stomach, the crickets started to do an orgy.

According to Gizmodo, the parasites shown on the video is horsehair worms also known as Gordian worm which is in the phylum Nematomorpha. UK Agriculture, Food and Environment states that horsehair worms develop as parasites in the bodies of grasshoppers, crickets, cockroaches and some beetles.

As creepy as it may sound, the report added that the horsehair worm has the ability to take control of its host's mind, turning the host into a zombie/follower. Once an insect is infected with it, the parasite will start to manipulate the way the host thinks. Eventually, the parasites will persuade the insect to go jump in the water where the parasites will start to emerge through holes bored in the insect's exoskeleton and mate in the water once out.

Parasitologist Ben Hanelt of the University of New Mexico told Wired "the worm appears to be producing large amounts of neurotransmitters. And the neurotransmitters that it's producing are thought to make the cricket basically act in ways that normally the cricket wouldn't act. And exactly which neurotransmitters these are and how they're affecting the crickets, that we don't know."

Meanwhile, a case of Gordian worm infecting humans have been noted in 2012. NCBI said both cases happened in Japan. Once case include an 80-year-old woman in Kyoto city who vomited and excreted two Gordiid worms and the other case includes a one-year-old boy in Nara city, Japan who was found with the Gordian worm on his mouth.
