200,000

The animal with the most taste buds is the catfish with 200,000. The catfish has about 20,000 taste buds in his mouth, or about twice as many as a human does. But, even weirder, the catfish has an additional 180,000 taste buds on the outside of his body, which means that in all, he has 20 times as many taste buds as humans do. These exterior taste buds help the catfish search for food and sense harmful substances as he scavenges in dark, muddy water.
