INVERSA Python Product

INVERSA™ Python

INVERSA™ Python is humanely sourced to protect the Greater Everglades ecosystem, North America’s last subtropical wilderness in the United States.

Material Overview

  • The Greater Everglades, an 11.5-million-acre subtropical wetland in Florida, is home to coastal mangroves, sawgrass marshes, and pine flatwoods that provide critical habitats for hundreds of species and coastal protection against flooding. Indigenous mammal populations play a key role in maintaining this balance, but non-native pythons are severely reducing their numbers through indiscriminate predation and are destroying this once-vibrant ecosystem.

  • Each INVERSA™ Python hide protects & restores up to —

    • 90% of native wildlife populations eliminated by pythons

    • 460 native animals that each 13-foot python consumes over its lifetime

    • 39 endangered species’ survival probabilities
