Catostomidae

Catostomidae

Their mouth is located on the underside of the head (subterminal), with thick, fleshy lips. Most species are less than 60 centimetres (2.0 ft) in length but the largest species can reach 100 centimetres (3.3 ft). They are distinguished from related fish by having a long pharyngeal bone in the throat, containing a single row of teeth.[1]
Catostomids are most often found in rivers but can be found in any freshwater environment. Their food ranges from detritus and bottom dwelling organisms (such as crustaceans and worms), to surface insects and small fishes.. They are distinguished from related fish by having a long pharyngeal bone in the throat, containing a single row of teeth.[1]
