How Long Is a Frog’s Tongue?

A frog’s tongue is about a third of the length of its entire body. In comparison, if a human had the same size tongue it would reach the belly button.

Unlike a human tongue that attaches at the back of the throat, a frog’s tongue attaches near the back of the jaw. When not in use, the tongue is folded up on the base of the mouth with the tip of the tongue pointing towards the back of the throat. A gland inside the mouth produces a sticky substance that allows the frog to accurately flip out the tongue and capture its prey.
