Reptiles The Secrets of the Chameleon's Tongue 4 minutes Small chameleons are able to project their tongues over a greater distance than larger specimens. Would you like to know more curiosities about their amazing tongues? Among animals, chameleons have strikingly distinctive features: they have zygodactylous feet, prehensile tails, colour-changing ability, panoramic eyes and ballistic projection of their tongue for prey-catching.

The chameleon's tongue is able to extend to twice the length of the body while unravelling telescopically. Past research has shown if the tongue were a car, it could accelerate from 0 to 60. The bone in a chameleon's tongue, known as the hyolingual apparatus, is a highly specialized structure that enables the chameleon to catch its prey with lightning speed. This bone is made up of several small bones connected by elastic tissues, and it is positioned at the base of the tongue. It is a Y-shaped bone structure that varies in length and shape, depending on the species of chameleon. This bone structure is responsible for allowing the chameleon to extend its tongue beyond its body length and change the pitch of its vocalizations. Base of the Tongue The launching mechanism of the chameleon's tongue is finally revealed. Chameleons' sticky tongues lash out at unsuspecting bugs with amazing speed. For almost a century, zoologists thought they had this feat of bioengineering figured out. But a new study shows they missed the most important bit.

The tongue consists of several key anatomical components, including the tongue proper, muscle system, and bone structure. The actual tongue of a chameleon is a long and slender organ, typically longer than its body length. The chameleon's tongue is said to unravel at the sort of speed that would see a car go from 0-60 mph in one hundredth of a second - and it can extend up to 2.5 body lengths when catching insects.. This tissue surrounds a bone at the core of the tongue and is surrounded itself by a muscle. Professor Moulton added: 'The muscle - the. At the core of a chameleon tongue is a slim, tubular bone wrapped in thin layers of elastic tissue. Enveloping all of this is a layer of muscle. The elastic tissue is made of collagen, a common biological material that gets remarkable stretchiness from its springlike fibers. Half the fibers spiral clockwise and half anticlockwise. The tongue of the chameleon rests on a rigid bone-like structure, the entoglossal process (called here the bone). The tongue complex itself is made of connected tubular units: the intralingual sheaths and the accelerator muscle (figure 2). For reference, we place a cylindrical coordinate system along the axis of the tongue, taken as the z-axis.

Chamaeleonidae) are a distinctive and highly specialized with 200 species described as of June 2015. The members of this family are best known for their distinct range of colors, being capable of shifting to different hues and degrees of brightness. A chameleon tongue's firing mechanism comprises coils of accelerator muscles which launch it and the retractor muscles. At rest, these sets of muscle are wrapped around a mouth bone-like.

Chameleon tongues are extremely fast and long. They can be anywhere from one to 1 1/2 times the bodylength of the owner and can rocket in and out with blinding speed. A 5 1/2 " tongue reaches full extension in 1/16th of a second, which is fast enough to snatch a fly in midair.
Chameleon Facts [Slideshow]
On average, a chameleon's tongue is roughly twice the length of its body. In humans, that would be a tongue about 10 to 12 feet (about 3 to 4 meters) long. To test his hypothesis, Anderson. The tongue of the chameleon rests on a rigid bone-like structure, the entoglossal process (called here the bone). The tongue complex itself is made of connected tubular units: the intralingual sheaths and the accelerator muscle (Fig. 2).
