STATES CHRONICLE – Scientists have revealed how frogs use their tongue as the most significant hunting tool they have. The fact that frogs can extend their tongues at great lengths being able to catch their prey is fascinating. Back 1849, Augustus Waller, a neurophysiologist developed and published on of the most accurate analysis regarding frog’s tongue.
The paper has been issued in the Philosophical Transactions magazine. He described that the tongue of a frog is used as an agent to capture prey, meaning it is used as a hunting tool. The frog throws its tongue out of its mouth and sticks to the prey. About a hundred years later, German scientists noted that they analyzed horned frogs which caught bugs in just 40 milliseconds.
Nevertheless, nobody was able to explain how frogs manage to maintain their control on the prey during these fast attacks. Researchers were aware of the fact that frog’s tongue is super-adhesive. A study from 2014 unveiled that the tongue of a frog is so powerful that it could heft items which are 1.4 times bigger than the frog’s body weight.
Some researchers linked this mechanism with the glue found on the back of post-it notes. Others have referred at frogs’ tongues as being similar to rolls of transparent tape. Alexis C. Noel, a biomechanics Ph.D. student at the Georgia Institute of Technology, saw a recording of an African bullfrog which was smashing digital bugs with its tongue, playing the mobile game ‘Ant Smasher.’
The researcher began to wonder whether scientists may have missed something during all this time when analyzing the mechanism of a frog’s tongue. Later, Noel discovered that the trick used by the frog in the video was called the frog spit. Frog spit changes its properties, modifying its structure from a viscous substance into a thinner fluid which goes back again.
Noel together with her colleagues developed a new study which was published on January 30 in the Journal of the Royal Society Interface. The interaction existing between the reversible frog saliva and a frog’s tongue permits these animals to catch their prey in just a few milliseconds. The mammalian maw, the organ which produces amphibians’ saliva is a slobbery area.
Where we have salivary glands which produce saliva, the frog has its tongue which produces spit. Even if a frog gets its tongue cut, the organ will continue to produce saliva.
