The beaded darter (Etheostoma clinton) is found in the upper Caddo and upper Ouachita Rivers upstream of the fall line in the Ouachita Mountains of Arkansas. It was named after the 42nd president of the United States Bill Clinton for his lasting environmental accomplishments in creating and expanding national monuments, preserving millions of acres of wilderness areas, his leadership and commitment during challenging economic times, and his continued commitment to global humanitarian issues and needs and peace.
