The Raycraft Ranch killifish or Raycraft poolfish (Empetrichthys latos concavus), a subspecies of the killifish Empetrichthys latos, was first described in 1948. This subspecies was restricted to a single spring on the Raycraft Ranch in the Pahrump Valley of Nye County, Nevada. It became extinct, most likely late in the 1950s, as a result of groundwater extraction and the filling in of the spring, along with competition from introduced carp species.
