The findings in the study highlight the ecological threat posed by Burmese pythons in Florida, where the invasive snakes have become established throughout much of South Florida after being introduced through the exotic pet trade.

Even a small number of sightings can signal a much larger hidden population.

Burmese pythons in Florida are devouring animals as small as rabbits and as big as deer and alligators. How they do it is fascinating and unsettling.

Burmese pythons are recognizable by more than their size. Hunters should be on the lookout for a telltale, arrow-shaped marking on the snake’s head, along with giraffe-like spots across its body and dark spots around its eyes. During the summer months, they’re most likely to be found sunning on levee banks or near trees.
