A freshwater fish related to carp, known as a barbel in English; also used in French heraldic terminology.
From Old French 'barbeau,' diminutive of 'barbe' (beard), named for the barbels or whisker-like sensory organs around the fish's mouth. The word has medieval French origins and was adopted into English heraldic vocabulary.
The barbeau got its name because its whisker-like barbels look like a little beard—and fishermen noticed that these whiskers are actually sensory organs that help the fish find food in murky water, so the 'beard' is really a fancy detection system!
