Every 29th of July people around the world celebrate the International Tiger Day. Tigers are known for their aggressive behaviour and ruthless attacks on humans, but nevertheless tigers are acknowledged as one of the finest creatures on the face of the earth. Even humans often like to refer to ourselves as tigers so others see them as tough.
Nine sub-species are known, although scientists often have discussions about this. Three of them are extinct: the Caspian, Bali and Java tiger. One sub-species can only exists in captivity at this moment: the South China tiger.
That makes there are only five sub-species left: the Amur tiger (formerly known as the Siberian tiger), the Indochinese tiger, the Malayan tiger, the Sumatra tiger and the Bengal tiger, the most common tiger of all.
Some say there are only two sub-spies: the one that lives on land and the one that lives on the islands. It is also said that the white tiger, the most rarest of all, is a sub-species.
Much more can be said about tigers. But pictures say more than words.
