Appearance change

There are tigers with distinct colors. Most tigers have orange fur with black stripes, and a white belly. The black stripes usually extend to the white underside. The stripes are vertical on the tiger's body, but the stripes are horizontal on the forehead, and the legs. The tail has rings, and the tail tip is black. The stripes are used to keep them camouflaged while hunting. No two tigers have the same pattern of stripes.[5] Most Bengal tigers have orange fur, but some Bengal tigers have white fur with black stripes, or that even have pure white fur. These white tigers are not albinos with red eyes. The white coat only appears once in every 100 births. The Bengal tiger is the national animal of Bangladesh and India.

Tigers vary in size depending on their subspecies. Siberian tigers are the largest. Males can grow to at least 9 ft (2.7 m) long (body length) and weigh about 900 lb (410 kg). Females are a bit smaller. Record weight for males is claimed as 890 lb (400 kg), but this cannot be confirmed.

Where they live change

Tigers can live in a variety of habitats. Mostly they need to hide, to be near a water source, and have enough prey to eat. Tigers are solitary and they all control large amounts of territory, the size of which depends on the availability of various food for tigers and prey.[6] According to Tigers-World, a male tiger may live and hunt in an area of 60 to 100 square kilometers (23 to 39 square miles). A female tiger may have 20 square kilometers (8 square miles).[7] According to the United States Fish and Wildlife Service, a single tiger can live in a territory as small as 21 square kilometers (8 square miles) to as large as 995 square kilometers (385 square miles).[8] Bengal tigers in particular live in many types of forests. These include the wet, evergreen of Assam and eastern Bengal; the swampy mangrove forest of the Ganges Delta; the deciduous forest of Nepal, and the thorn forests of the Western Ghats.

Subspecies change

As previously thought, the tiger had five living subspecies. In this context, 'recently' means in the last two centuries. Three tiger subspecies are extinct (†).

However, in 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group revised felid taxonomy and recognized the tiger populations in continental Asia as P. t. tigris, and those in the Sunda Islands as P. t. sondaica.[9]

Tigers and humans change

Tigers are becoming rare, because people hunt them for their coat (skin) and destroy the habitats they live in. The Bengal tiger has the largest population with 3,500 left in the wild. To help keep the tiger population, tigers are often placed in zoos. In order for tigers to survive into the next century, governments throughout the tigers’ range must show greater determination and commitment to conserve tigers and their habitats.[10]

Chinese tigers have been used for centuries in traditional Chinese medicine. Body parts such as their whiskers and bones are used to treat things such as toothaches, malaria, and burns.

Tigers also kill and eat peoples' livestock, which are easier to hunt than their typical prey, because they are often in fenced or closed areas and livestock may not be able to flee. Sometimes tigers hunt people as prey and eat them, because they are either too old, injured, or ill to hunt their typical animal prey which are much faster than people. These too are a reason why tigers are killed by people.

Diet change

Tigers eat many types of prey, mostly ungulates. Some examples are deer, monkeys, wild rabbits, wild pigs, tapirs, water buffalo and other animals found in Asia. They also eat birds, reptiles and fish. They also prey on other predators, including dogs, leopards, bears, snakes and crocodiles.[11] All are carnivores (meat eaters). Some tigers may eat up to 50 pounds (23 kilograms) of meat a day. Tigers kill their prey by clamping down on the prey's throat and suffocating it.[12]
