Caption: Coqui frog tongue with taste disk / bud (Eleutherodactylus coqui). The frog's tongue is highly specialized. Normally, the tip of its tongue is folded backward toward the throat. From this position the frog can flick it out rapidly to grasp any passing prey. To better hold this prey, the tongue is sticky. The frog taste disc / bud (TD) is apparently the largest gustatory organ found in vertebrates and differentiates into a specialized taste disk / bud (fungiform papilla). There are two main cell types (sensory and sustentacular).
