Chameleons are known for their color-changing trickery and tongue-lashing feats. Now, scientists have found the tiniest of these clever reptiles also pack the most power in their elastic tongues. Here's a look at the amazing animals and their tongue-y feats. [Read full article on tiny chameleons]

Tiny but mighty

A tiny Rhampholeon spinosus chameleon snags a cricket with its tongue. New research published January 4 in the journal Scientific Reports finds that these chameleons can accelerate their tongues at 264 times the force of gravity. (Photo Credit: © Christopher Anderson)

Titanic tongues

A Parson's chameleon (Calumma parsonii parsonii). Brown University research Christopher Anderson used high-speed video to record this species capturing a cricket with its tongue. He recorded a male Parson's chameleon 7.5 inches long (19 centimeters) flicking its tongue out 6.7 inches (17.1 centimeters), nearly its entire body length. Some chameleons can extend their tongues up to 2.5 body lengths from their mouths. (Photo Credit: © Christopher Anderson)

Madagascar leaf chameleon

Brookesia supercillaris, the Madagascar leaf chameleon. In a test of a 1.8-inch-long (4.5 centimeter) chameleon of this species, researchers found that the animal could extend its tongue at least 3.5 in. (9 cm), reaching a peak acceleration of 4.9 meters per second (11 mph). (Photo Credit: © Christopher Anderson)

Tongue in action

A screenshot from a high-speed video of Trioceros hoehnelii, or von Höhnel's chameleon, snagging a cricket. These chameleons grow to about 10 inches (25 cm) long. To project their tongues in the blink of an eye, chameleons use bone, muscle and connective tissue. The tongue attaches to the hyoid bone, around which a tubular sheath of muscle wraps. When this tubular muscle contracts, it stretches connective tissue between the muscle and the bone. Like a stretched rubber band, this tissue recoils dramatically when let go, enabling a massively powerful tongue acceleration. (Photo Credit: © Christopher Anderson)

Tiny hunters

Triceros hoehnelii prepares to chow down on its cricket quarry. Pound-for-pound, small animals have higher metabolic needs than larger animals. Fortunately, smaller chameleons can shoot their tongues out farther and accelerate them faster than their larger cousins, helping them hunt effectively. (Photo Credit: © Christopher Anderson)

What a cutie!

Champion chameleon

What a big nose you have! A male Kinyongia fischeri, or Fischer's two-horned chameleon, perches on a branch. In the lab, a 4.7-inch-long (12 cm) individual of this species shot its tongue out 2 inches longer than its body length, or a distance of 6.7 inches (17.1 cm). (Photo Credit: © Christopher Anderson)

Becoming a mama

A Triceros montium, or Cameroon mountain two-horned chameleon, lays eggs. Among amniotes (reptiles, mammals and birds that lay eggs on land or keep them in the female's body), chameleons have the highest capacity for explosive power. Their tongues release energy at a rate of up to 14,000 watts per kilogram, thanks to their elastic tissues. In comparison, the peak power seen in vertebrate muscles is 1,100 watts per kilogram in the beating wing of a quail. Only some species of salamanders have more impressive tongues than the smallest chameleons. (Photo Credit: © Christopher Anderson)

A Madagascar native

Furcifer lateralis, a chameleon species found only in Madagascar. These colorful chameleons grow up to about 10 inches (25 cm) in length and can change colors from dark to light. (Photo Credit: © Christopher Anderson)

Losing ground

Trioceros montium, a colorful chameleon species found in Cameroon. In one experiment, a 4-inch-long (11 cm) individual of this species stuck its tongue out 5.3 inches (13.5 cm) in pursuit of a cricket meal. This beautiful species is listed as "near threatened" by the International Union for Conservation of Nature, because it is losing habitat and possibly being over-collected for the international pet trade.
