The tiny golden mantella frog; one of the most endangered animals in the world.

Scientists at Chester Zoo in the UK are injecting them with harmless, fluorescent silicon.

This allows them to track the amphibians in the wild, and learn more about the frogs' forest habitat in Madagascar.

They hope it will help create a bright future for these colourful creatures.
