Deer are the only group of animals in the world to have antlers. Antlers are the fastest growing living tissue in the world! There are over 60 different species of deer worldwide. Deer are present on all continents except Antarctica. They can live in a range of habitats, from mountainous areas to warm and wet rainforests. The Barbary red deer is the only species present in Africa A male deer is called a buck but some larger males are referred to as stags. A Female deer is called a doe or hind. A young deer is called a fawn. Bucks and does can be distinguished from each other by the presence of antlers. Female Caribou (Reindeer) are the only female deer which grow antlers All species of deer have antlers, with the exception of the Chinese water deer. Instead of antlers, they have long canine teeth which can be as long as 8cm! Each year, antlers fall off and regrow. As they regrow, they are covered in a furry coat called velvet. The velvet is rich in nerves and blood vessels, allowing the antlers to regrow quickly During the mating season, or ‘the rut’, bucks will use their antlers to fight over does. The winner is the buck who manages to overpower the other. Red deer can be heard roaring in the rut to attract females The length of pregnancy in deer varies according to size. Generally, the larger the species the longer the gestation. It is dependent on where a species lives as to when it will breed. Deer in tropical climates can breed all year round When most deer are born, they have white spots which disappear as they mature. The spots help fawns to blend into their background, acting as camouflage A fawn can normally walk within half an hour of being born. Fawns do not have a smell, helping them avoid predators All species of deer have a four chamber stomach which allows them to chew the cud. This is a processes of partially chewing food, regurgitating it, and chewing it again to make it easier to digest.

Horses and humans have an ancient relationship.Asian nomads probably domesticated the first horses some 4,000 years ago, and the animals remained essential to many human societies until the advent of the engine. Horses still hold a place of honor in many cultures, often linked to heroic exploits in war. There is only one species of domestic horse, but around 400 different breeds that specialize in everything from pulling wagons to racing. All horses are grazers. While most horses are domestic, others remain wild. Feral horses are the descendents of once-tame animals that have run free for generations. Groups of such horses can be found in many places around the world. Free-roaming North American mustangs, for example, are the descendents of horses brought by Europeans more than 400 years ago.Wild horses generally gather in groups of 3 to 20 animals. A stallion (mature male) leads the group, which consists of mares (females) and young foals. When young males become colts, at around two years of age, the stallion drives them away. The colts then roam with other young males until they can gather their own band of females.

The tiger (Panthera tigris) is the largest cat species and a member of the genus Panthera. It is most recognisable for its dark vertical stripes on orangish-brown fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own. The tiger once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin, and in the south from the foothills of the Himalayas to Bali in the Sunda islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated in Western and Central Asia, from the islands of Java and Bali, and in large areas of Southeast and South Asia and China. Today's tiger range is fragmented, stretching from Siberian temperate forests to subtropical and tropical forests on the Indian subcontinent and Sumatra. The tiger is listed as Endangered on the IUCN Red List since 1986. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, down from around 100,000 at the start of the 20th century, with most remaining populations occurring in small pockets isolated from each other. Major reasons for population decline include habitat destruction, habitat fragmentation and poaching. This, coupled with the fact that it lives in some of the more densely populated places on Earth, has caused significant conflicts with humans.
