MIAMI (AP) - Researchers have discovered something new about Burmese pythons: the invasive snakes are really good at finding their way home.

Researchers caught six pythons in south Florida's EvergladesNational Park, implanted radio transmitters under their skins and released them up to two dozen miles from where they were captured. Surprisingly, the snakes found their way home within months.

According to research being published Wednesday in the Journal Biology Letters, the pythons slithered with a purpose instead of moving randomly across the wetlands. It's unclear how the snakes mapped their routes.

Unfortunately, the discovery about pythons' unusual navigational abilities doesn't much help wildlife agencies desperately trying to curb the python population in the fragile wetlands. The tan, splotchy snakes are notoriously hard to spot in the everglades even when tracked with transmitters.
