Final answer:
The frog's tongue is attached at the front of its mouth and is long, sticky, and adept at rapidly capturing insects, contrasting with the human tongue, which is attached at the back and utilized for taste and manipulating food within the mouth.
Step-by-step explanation:
The main difference between a frog tongue and a human tongue is their attachment and function during feeding. A frog's tongue is attached at the front of its mouth, rather than at the back like a human's. Frogs use their long, sticky tongues to capture prey, with the tongue able to extend rapidly, often reaching a length of about one-third of the frog's body. In striking contrast, human tongues are anchored at the back of the mouth and are primarily used for taste and manipulating food within the mouth rather than capturing it from a distance.When a frog catches an insect, it does so by shooting its sticky tongue out, wrapping it around the prey, and quickly retracting it to throw the food down its throat, a process that occurs as fast as a human blink. Frog's tongues can also release a sticky substance to ensure their prey does not escape during this swift motion.Aside from feeding mechanisms, frogs and humans differ in other anatomical and physiological aspects. For instance, frogs are amphibians with moist skin suitable for their partly aquatic lifestyle, while humans are mammals with overall dry skin adapted to a terrestrial life. Frogs have much longer back legs for jumping, a muscular feature absent in humans whose legs are adapted for bipedal walking and running.
