Catfish whiskers, also known as barbels, are flexible fleshy filaments that extend from the head of the fish. They are made of a dense network of blood vessels and nerve endings, and are highly sensitive to touch and taste. While catfish whiskers are not sharp or barbed, they can potentially enter human skin if the fish is startled or agitated. However, the risk of this happening is relatively low and it is not considered a common occurrence.
