The animals (and one plant) highlighted by the group range from the relatively unknown and small Tan Riffleshell, a freshwater mussel found in only five rivers in the eastern US, to the large and majestic Bowhead Whale, believed to be among the oldest mammals on earth and the only whale that lives exclusively in arctic waters. The other eight species examined in the report include: the Dunes Sagebrush Lizard, the Graham’s Penstemon (a wildflower), the Greater Sage Grouse, the Kemp’s Ridley Sea Turtle, the Kentucky Arrow Darter, the Spectacled Eider, the Whooping Crane, and the Wyoming Pocket Gopher. Receiving the 'activist's choice award' from the voting members was the Polar Bear, chosen because it was "the species they were most concerned about."
