Horse
The horse adapted to survive in areas of wide-open terrain with sparse vegetation, surviving in an ecosystem where other large grazing animals, especially ruminants, could not. Horses and other equids are odd-toed ungulates of the order Perissodactyla, a group of mammals that was dominant during the Tertiary period. In the past, this order contained 14 families, but only three—Equidae (the horse and related species), Tapiridae (the tapir), and Rhinocerotidae (the rhinoceroses)—have survived to the present day.
Ecnomiohyla
Ecnomiohyla, commonly known as fringe-limbed treefrogs or marvelous frogs, is a genus of frogs in the family Hylidae. This genus was erected in 2005 following a major revision of Hylidae. The ten original species in this genus ("E. rabborum" and "E. sukia" are later discoveries) were previously placed in the genus "Hyla". The generic name "Ecnomiohyla" comes from Greek "ecnomios" ("marvelous" or "unusual") and Hylas, the companion of Hercules.
