Originally described as a subspecies of the greater long-nosed bat, it was later considered a subspecies of the southern long-nosed bat, before being confirmed as a distinct species. Enthusiasts for the bats often refer to them simply as leptos because they are the best known members of the genus Leptonycteris. The scientific name is derived from the type locality, near Yerbabuena in Guerrero, Mexico.[from wikipedia]

Oakland Zoo, in the past known as the Knowland Zoo, is a 100-acre (40 ha) zoo located in southeastern Oakland, California, United States. Most of its animals are kept in relatively "natural" habitats, and expanded natural habitats are planned. The Wayne and Gladys Valley Children's Zoo which opened in 2005 is a good example of the zoo's plans for the future, with interactive exhibits, state of the art animal housing facilities and children's play areas. The zoo is nationally known for its excellent elephant exhibit and has been praised for allowing their elephants to roam freely.[from wikipedia]

Bats are mammals of the order Chiroptera whose forelimbs form webbed wings; they are the only mammals naturally capable of true and sustained flight. Bats are more manoeuvrable than birds, using their very long spread-out digits which are covered with a thin membrane or patagium.Bats are mammals of the order Chiroptera whose forelimbs form webbed wings; they are the only mammals naturally capable of true and sustained flight.
