Small chameleons have fastest tongues
Chameleons' tongues are some of the fastest in the animal kingdom. But it's the smallest ones that have the fastest tongues, according to a new study.
Researchers filmed the tongues of different chameleons attacking crickets.
Across 20 species, they found that smaller species' tongues could accelerate five times faster than that of the largest chameleon.
That's because small chameleons have larger tongues compared to their body size, because they need more food to survive.
