The great hammerhead ( Sphyrna mokarran), a member of the same taxonomic order as the tiger shark, has a similar or even greater average body length, but is lighter and less bulky, with a maximum known weight of 580 kg (1,280 lb). Some other species such as megamouth sharks ( Megachasma pelagios), Pacific sleeper sharks ( Somniosus pacificus), Greenland sharks ( Somniosus microcephalus), and bluntnose sixgill sharks ( Hexanchus griseus) broadly overlap in size with the tiger shark, but as these species are comparatively poorly studied, whether their typical mature size matches that of the tiger shark is unclear. This makes it the second-largest predatory shark, after the great white. Īmong the largest extant sharks, the tiger shark ranks in average size only behind the whale shark ( Rhincodon typus), the basking shark ( Cetorhinus maximus), and the great white shark ( Carcharodon carcharias). A 2019 study suggested that it would have reached 8 m (26 ft) in maximum length.
#Lemon stripes verification#
Some papers have accepted a record of an exceptional 7.4 m (24 ft 3 in) length for a tiger shark, but since this is far larger than any scientifically observed specimen, verification would be needed.
Even larger unconfirmed catches have been claimed. One pregnant female caught off Australia reportedly measured 5.5 m (18 ft 1 in) long and weighed 1,524 kg (3,360 lb). Weights of particularly large female tiger sharks can exceed 900 kg (2,000 lb). Exceptionally large females reportedly can measure over 5 m (16 ft 5 in), and the largest males 4 m (13 ft 1 in). Mature females are often over 3.7 m (12 ft 2 in) while mature males rarely get that large. It is dimorphic, with females being the larger sex. The tiger shark commonly attains adult length of 3.25–4.25 m (10 ft 8 in – 13 ft 11 in) and weighs often around 175 to 635 kg (386 to 1,400 lb). This family consists of mostly slender but powerful mid- to large-sized sharks and includes some other well-known sharks, such as the blue shark ( Prionace glauca), lemon shark ( Negaprion brevirostris), and bull shark ( Carcharhinus leucas). It is the largest member of the Carcharhinidae family, commonly referred to as requiem sharks. Members of this order are characterized by the presence of a nictitating membrane over the eyes, two dorsal fins, an anal fin, and five gill slits. The tiger shark is a member of the order Carcharhiniformes, the most species-rich order of sharks, with more than 270 species also including the small catsharks and hammerhead sharks. It is often colloquially called the man-eater shark. The genus, Galeocerdo, is derived from the Greek galeos, which means shark, and kerdo, the word for fox. Müller and Henle in 1837 renamed it Galeocerdo tigrinus. The shark was first described by Peron and Lesueur in 1822, and was given the name Squalus cuvier. The tiger shark is second only to the great white in recorded fatal attacks on humans, but these events are still exceedingly rare. It is considered a near threatened species due to finning and fishing by humans. Though apex predators, tiger sharks are sometimes taken as prey by groups of killer whales. It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. 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.
The tiger shark is a solitary, mostly nocturnal hunter. Its name derives from the dark stripes down its body, which resemble a tiger's pattern, but fade as the shark matures. Populations are found in many tropical and temperate waters, especially around central Pacific islands. It is a large macropredator, capable of attaining a length over 5 m (16 ft 5 in). The tiger shark ( Galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus Galeocerdo. Galeocerdo tigrinus Müller and Henle, 1837.
