fish have slender, pendulous tactile organs near the mouth. These are often referred to as "whiskers", although they are more correctly termed barbels. Fish that have barbels include the catfish, carp, goatfish, hagfish, sturgeon, zebrafish and some species of shark. The Pimelodidae are a family of catfishes (order Siluriformes) commonly known as the long-whiskered catfishes. In pterosaurs Anurognathid pterosaurs had a rugose (wrinkled) jaw texture that has been interpreted as the attachment sites for vibrissae, though actual vibrissae have not been recorded. More recently, a specific type of feathers, has been found around anurognathid mouths.
