Caspian tiger The Caspian tiger ("Panthera tigris virgata") is an extinct tiger subspecies, which inhabited the sparse forests and riverine corridors west and south of the Caspian Sea, from Turkey, Mesopotamia, Iran and the Caucasus, through Central Asia to the Takla Makan desert of Xinjiang in China, until the end of the 20th century. Depending on the region, it was also called Hyrcanian tiger, Turanian tiger, Persian tiger, and "Babre Mazandaran" (Persian: ‎ ‎ , Tiger of Mazandaran). It was one of the largest big cats to have ever lived and was described as being intermediate in size between Siberian and Bengal tigers.
Tiger shark The tiger shark ("Galeocerdo cuvier") is a species of requiem shark and the only extant member of the genus Galeocerdo. Commonly known as the "Sea Tiger", the tiger shark is a relatively large macropredator, capable of attaining a length over 5 m . It is found in many tropical and temperate waters, and it is especially common around central Pacific islands. Its name derives from the dark stripes down its body which resemble a tiger's pattern, which fade as the shark matures.
