French tech company Sigfox has developed a bite-size tracker that can be inserted into the horns of rhinos to help conservationists monitor and protect the endangered species.

With the dramatic decline of animal species in the past century mostly due to poaching and urban expansion, wildlife organizations have turned to technology to help safeguard species being pushed towards extinction.

The global number of rhinos dwindled to about 20,000 a decade ago due to relentless poaching, though they have rebounded to about 29,000 thanks to conservation efforts.
