Ecologist Kristoffer Wild spent a year in the Australian outback fitting bearded dragons with hand-sewn jackets with GPS trackers to track every second of the lizards' lives.

A study tracked 40 bearded dragons using hand-sewn outfits fitted with sensors that monitored movement, temperature and acceleration.

The study found faster lizards were more likely to die than slower ones.
