The papilla, in certain kinds of fish, particularly rays, sharks, and catfish, are small lumps of dermal tissue found in the mouth, where they’re “distributed uniformly on the tongue, palate, and pharynx”. Unlike humans, fish have little or nothing in the way of a tongue, and those which have such an organ do not use it for tasting, however merely for cushioning the mouth and manipulating things inside it. The papillae of the fish, and the style buds discovered on them, are due to this fact located on the inside or exterior surfaces of the mouth. Most sometimes, these are found on the floor of the mouth, or on the upper lip. B. G. Kapoor, H. E. Evans, E. A.

They “venture barely above the encompassing multi-layered epithelium”, and the taste buds of the fish are “situated along the crest or on the apex of the papillae”.
