Razorback sucker

(重定向自Xyrauchen texanus)
Adult razorback sucker

The razorback sucker (Xyrauchen texanus) is a fresh water sucker fish found in rivers and lakes in the western United States. It can grow to a meter in length and is recognisable by the keel between its head and dorsal fin. It used to inhabit much of the Colorado River basin but commercial fishing, river damming and habitat loss have caused great declines in populations. It is now restricted to the Colorado River upstream of the Grand Canyon, and to three lakes, Lake Mead, Lake Mohave and Lake Havasu.
