Giant pythons have 'homing instinct'
Giant Burmese pythons have map and compass senses which help them travel "home" over vast distances, scientists have been surprised to discover.
Pythons captured and relocated in Florida's Everglades - where they are an invasive species - returned 23 miles (36km) to their original start point.
It is the first evidence that snakes may share a similar magnetic compass to other reptiles, such as sea turtles.
The findings are published in the Royal Society journal Biology Letters.
