New research reveals Burmese pythons can consume dramatically larger prey than previously thought, raising fresh concerns about their impact on Florida’s ecosystem.
Why it matters: This discovery helps scientists better predict the ecological damage these invasive snakes could cause as they spread across the Southeast US. The findings are crucial for wildlife management and conservation efforts.
- Burmese pythons have already devastated populations of native Florida wildlife, including foxes, bobcats, and raccoons.
Key finding: The largest pythons studied had a 40% larger gape area than predicted, enabling them to swallow prey with up to a 32-inch circumference.
“Watching an invasive apex predator swallow a full-sized deer in front of you is something that you will never forget.”

The process:
- Researchers examined three massive pythons (15-19 feet long)
- Measured gape size and cranial anatomy
- Tracked 120 radio-tagged “scout snakes”
- Documented actual predation events
Keep in mind: Extra-large pythons (>16 feet) are rare, representing less than 1% of captured snakes.
Real-world impact: The findings suggest these snakes pose an even greater threat to wildlife than previously understood:
- 770 removed pythons could potentially consume 13,000 pounds of prey
- Their spread threatens wildlife beyond Florida
- Pet trade releases continue to fuel the problem
TL;DR
- Burmese pythons can swallow prey 18% larger in diameter than previously thought, with a 40% larger gape area.
- A single python can consume prey weighing up to two-thirds of its own body mass.
- The findings help predict potential ecological damage as pythons spread to new areas.
