Researchers proves that
chameleon's tongue is ridiculously fast. Some of the world's smallest
chameleons have the world's fastest tongues. In automotive terms, the tongue
could go from 0 to 60 miles per hour in a hundredth of a second, though it only
needs about 20 milliseconds to snag a pey.
Chameleons spring-load the elastic
tissue in their tongue, catapulting it toward prey when they strike, and giving
them the highest acceleration and power output of any reptile, bird, or mammal.
Chameleon's long, elastic tongues
are one of the fastest muscles in the animal kingdom, extending more than twice
their body length and packing 14,000 watts of power per kilo. But it is the
smallest species that strike fastest, according to a new study.
Researchers filmed tongue strikes
of chameleons attacking a suspended cricket, at 3000 frames per second. They
found that the animal's tongues are capable of impressive acceleration, doing 0
kilometers to 100 kilometers per hour in one-hundredth of a second, twice as
fast as the fastest car.
The secret of chameleons is that
they don’t just use spontaneous
muscle power to fling their tongues. They preload most of the motion’s total energy into elastic
tissues in their tongue. The recoil of those tissues greatly augments what
muscle alone can do on the fly to catch a fly.
Various scientific reports,
suggest that, the motion has the highest acceleration and power output produced
per kilogram of muscle mass by any reptile, bird, or mammal and is the second
most powerful among any kind of vertebrate (only a salamander outdoes it). The
total power output of the plucky R. spinosus chameleon’s tongue was 14,040 watts per
kilogram.
