Nature photographer Jeff Cremer was working in the jungles of Tambopata, Peru a few years ago, when he uncovered several dozen worms in the soil glowing a strange green color.
Local entomologists had never seen anything like it before in the region but came to the conclusion that the animal is possibly the larvae of an unknown species of click beetle. He initially posted pictures of his findings on Reddit to help solve the mystery.
The .5-inch long worms have since been determined to be carnivorous as well, and use the glowing light to attract their prey into their terrifying jaws before chowing down.
Entomologist Aaron Pomerantz recently took a trip down to Peru with Cremer to investigate further, which you can watch in the video above.
