Of all the living creatures on Earth, catfish has most taste buds. The average person has about 10,000 taste buds. Catfish (order Siluriformes) typically have more than 100,000 taste buds. Some large catfish can have as many as 175,000. Taste buds are located all over the catfish's body, but are most concentrated on the four pairs of whiskers around its mouth. These whiskers, called barbells, act as antennae. Along with the thousands of buds along their body, the whiskers allow the fish to not only taste when dinner is nearby, but also hone in on its exact location. A highly developed sense of taste is critical for catfish, which do their hunting in extremely muddy, murky waters where visibility is low. Chickens, who have only about 24 taste buds, have the fewest taste buds.

Piranhas are known for their razor-sharp teeth and relentless bite. (The word piranha literally translates to “tooth fish” in the Brazilian language Tupí.) Adults have a single row of interlocking teeth lining the jaw. True piranhas have tricuspid teeth, with a more pronounced middle cuspid or crown, about 4 millimeters tall. The shape of a piranha’s tooth is frequently compared to that of a blade and is clearly adapted to suit their meat-eating diet. The actual tooth enamel structure is similar to that of sharks. It’s not uncommon for piranhas to lose teeth throughout their lifetime. But, while sharks replace their teeth individually, piranhas replace teeth in quarters multiple times throughout their lifespan, which reaches up to eight years in captivity. A piranha with half of its lower jaw chompers missing isn’t out of the ordinary.
