Mysterious glowing worms found in the Amazon

A glowing worm was discovered in the Peruvian rainforest that is making researchers scratch their heads.

Photographer Jeff Cremer found the unique glowing creatures sitting inside a dirt wall in Peru. He shared the photos with entomologists who went to the Amazon to investigate.

The researchers found these mysterious 'glow worms' that are believed to be in their larval stage and part of a beetle species, though the exact species is unknown.

Researches say they are predatory. They observed the worms using their beautiful light to lure flies and ants for food.
