The tools for eating food are different: the carp's foraging tool is its own beard, and the wild Yellow River carp needs to find food by itself, so the beard of the wild Yellow River carp is longer and thicker. Common domestic carp do not need to find their own food, and their beards are not often used, so their beards are thinner and smaller.
