General Description

Razorback Sucker (Xyrauchen texanus) is a large (over 0.91 m long) fish that occurs in the Colorado River system, though rarely above the Grand Canyon. In New Mexico they occur in Lake Mojave on the Colorado River and have been reintroduced to the San Juan River. They inhabit deep, fast flowing water in large rivers and backwaters and can also be found in reservoirs. They are threatened by non-native fish predation and loss of habitat.
