Detailed explanation-1: -Chameleons don’t wrap their tongues around their prey, which means that the food they catch must somehow stick to their tongue. In a new paper in Nature Physics, Damman and colleagues show that chameleons produce a viscous, sticky mucus on the tip of their tongue that’s 400 times thicker than human saliva.

Detailed explanation-2: -But chameleon evolution has added to the arsenal of lingual tricks. The hollow tongue sheathes over a long, tapering cartilaginous spike called the hyoid horn.

Detailed explanation-3: -Chameleons are arboreal, meaning they spend the majority of their time up in the trees. They are perfectly adapted to this lifestyle. Chameleons’ feet split at nearly a 180 degree angle allowing for a superior grip on the branches where they live. Another great climbing adaptation is the tail.

Detailed explanation-4: -Frogs have long sticky tongues, it throws its sticky tongue out to its target, the insect gets stuck on the tongues and then the frog rolls back the tongue inside its mouth and swallows its prey.
