What is a "barbel"?

A barbel is a sensory appendage found on the heads of certain fish species. It typically appears as a slender, fleshy projection extending from the area around the mouth. Barbels are equipped with numerous taste buds and sensory cells, allowing fish to detect and locate food sources in their environment. These specialized organs help fish navigate murky waters and search for prey or edible particles, enhancing their ability to survive and thrive in various aquatic habitats.
