Abstract: Mountain suckers are small, torpedo-shaped fish. Like other suckers, they have large mouths with large fleshy lips, which they can extend to feed, but no teeth. The lower jaw is edged with cartilage. The lower lip is shaped like the tail flukes of a whale and covered with papillae (sensory organs for feeding). Mountain suckers have a deep notch where the upper and lower lips join; in other suckers the two lips come together like one. The back of their body is dark green, grey or brown, speckled with black. The sensory line down their sides (lateral line) is not very obvious. The belly of the fish is pale yellow to white. Fins are normally colourless. Breeding fish are brightly coloured with an orange to deep red band on their flanks and darker fins. Very young suckers closely resemble minnows with the mouth placed at the end of the nose. The mouth migrates under the head as they grow. Mountain sucker fry are strongly marked with dark green backs, white bellies, and three dark crescent-shaped markings behind the gill cover.
