The diversity of animal tongues is remarkable! From the sticky ones of chameleons to the blue prehensile ones of giraffes we have a fascinating gallery of images for you. Here are some fascinating facts: * A giraffe uses its prehensile, blue tongue to reach around acacia thorns and grab the tasty leaves. * Sun Bears have the longest tongues of all bears at almost 10" long! * Geckos lick their eyes to clean them because most species lack eyelids. * Whitemargin Stargazer fish bury themselves in the sand and extend their tongues as a lure. * At two-feet-long and only half-an-inch wide, the anteater’s tongue is perfectly adapted to collect insect prey. * A penguin's tongue, though lacking taste buds, has large keratinized bristles that help grip the krill or fish as it enters the mouth
