Invasive python devours deer bigger than itself in Florida

Researchers studying invasive Burmese pythons in Florida came upon something they'd never seen before: a 3.4-metre-long(11-foot-long) python had consumed an entire deer that weighed more than the snake itself.

The wildlife biologists tracking the slithery creatures stumbled upon a bloated female snake in Collier Seminole State Park, and when they moved the creature it began regurgitating a white-tailed deer fawn, the researchers reported in an article on the blogging site Medium.

The fawn had a mass of 15.88 kilograms (35 pounds); the snake 14.29 kilograms (31.5 pounds).

"We were sitting there just trying to process that an animal this size could get its head around what turned out to be a deer," biologist IanBartoszektold the Naples Daily News. "It's surreal to see that in the field."

Bartoszek said it was the largest python-to-prey weight difference he had measured.

Burmese pythons, which can grow nearly sixmetres (20-feet long), were brought to South Florida as pets in the late 1970s. They were released into the wild, and have become a problematic invasive species.

White-tailed deer are an important food source for Florida's endangered panthers, so the researchers are concerned the pervasive snakes could also impact the health of the big cats.

If the snake had been left in the wild, it would have digested the entire deer, Bartoszek said.

He said the predator-to-prey size ratio stunned his team.

"It showed my team and myself what we were actually dealing with out there, what this python is capable of," he told the newspaper.

The findings will be published in the March 2018 issue ofHerpetological Review.
