African elephants are the largest land animals on Earth. They are slightly larger than their Asian cousins and can be identified by their larger ears that look somewhat like the continent of Africa. (Asian elephants have smaller, rounded ears.)
The Dusky Dolphin is a small species of dolphin that is found inhabiting the cooler waters along continental shelves throughout the southern hemisphere. This distinctive looking cetacean is closely related to other large marine animals including other dolphins, porpoises and whales but despite their fish-like appearance Dusky Dolphins are true mammals that both breathe air in and out of their lungs and also suckle their young on milk produced by the mother's mammary glands. Dusky Dolphins are widespread throughout the southern hemisphere with three species being recognised that have been grouped by their geographical range, with one found off the coast of South America, one near South Africa

The Vampire Bat is a small species of Bat, native to the tropics of Central and South America. There are three recognised sub-species of Vampire Bat, all of which are in a genus of their own despite their obvious similarities. The Common Vampire Bat, the Hairy-Legged Vampire Bat and the White-Winged Vampire Bat are all closely related and share the same unique feeding habits, as they are the only known mammals that feed entirely on blood. Over time, Vampire Bats have perfectly adapted to the consumption of their only food source, with a leaf-like heat sensor on the end of their nose which detects where the warm blood is flowing closest to the skin.
