Whale is the common name for a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale),
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.

The ferret is a domestic animal thought to be native to Europe. The ferret is thought to be a subspecies of polecat and the ferret has the same long shaped body as a polecat and a weasel.
The ferret is thought to have been domesticated around 2,500 years ago, which is roughly the same time that a number of animals such as the donkey and goat were put to domestic use. The ferret is used to help farmers hunt out rabbits and the ferret does this by crawling into the rabbit burrows, with the ferret using its incredibly shaped flexible body to its advantage as a ferret is often small than many rabbits. The rabbit is scared out of the burrow by the invading ferret and uses one of the many bu
