Tiger Shark - Galeocerdo cuvier
The tiger shark (Galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus Galeocerdo. It is a large macropredator, capable of attaining a length over 5 m (16 ft 5 in). Populations are found in many tropical and temperate waters, especially around central Pacific islands. Its name derives from the dark stripes down its body, which resemble a tiger's pattern, but fade as the shark matures. The tiger shark is a solitary, mostly nocturnal hunter. It is notable for having the widest food spectrum of all sharks, with a range of prey that includes crustaceans, fish, seals, birds, squid, turtles, sea snakes, dolphins, and even other smaller sharks. It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. Though apex predators, tiger sharks are sometimes taken by groups of killer whales. It is considered a near threatened species due to finning and fishing by humans. The tiger shark commonly attains a length of 3.25–4.25 m (10 ft 8 in–13 ft 11 in) and weighs around 385–635 kg (849–1,400 lb). It is dimorphic, with exceptionally large females reportedly measuring over 5 m (16 ft 5 in), and the largest males 4 m (13 ft 1 in). Weights of particularly large female tiger sharks can exceed 900 kg (2,000 lb).

Gigantophis garstini
Gigantophis garstini was a prehistoric snake which may have measured more than 10 metres (33 ft), larger than any living species of snake. It once took the mantle of largest snake before Titanoboa, which was discovered in Colombia in 2009. Gigantophis lived approximately 40 million years ago in the southern Sahara where Egypt and Algeria are now situated. The species is known only from a small number of fossils, and may have preyed on basal proboscideans, pig-sized ancestors of modern elephants. Gigantophis is classified as a member of the madtsoiid family. Jason Head, of the Smithsonian Institution in Washington, D.C., has compared the fossil vertebrae of a Gigantophis to those of the largest modern snakes, and concluded that the extinct snake could grow to 9.3 metres (31 ft) to 10.7 metres (35 ft) in length. If 10.7 metres (35 ft), it would have been more than 10 percent longer than its largest living relatives.
