It ranks second on the list of number of recorded bites on humans, behind only the great white shark. The Tiger Shark is found in many tropical and temperate waters worldwide. Its head is somewhat wedge-shaped, which makes it easy to turn quickly to one side. A tiger shark generally has long fins to provide lift as the shark maneuvers through water, while the long upper tail provides bursts of speed.

The male inserts one of his claspers into the female's genital opening (cloaca), acting as a guide for the sperm. , The broad, heavily calcified jaws and nearly terminal mouth, combined with robust, serrated teeth, enable the tiger shark to take on these large prey.  In addition, excellent eyesight and acute sense of smell enable it to react to faint traces of blood and follow them to the source.  While the tiger shark is considered to be one of the sharks most dangerous to humans, its bite rate is low.

How long tiger sharks live is unknown, but they can live longer than 12 years. 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.  They often visit shallow reefs, harbors, and canals, creating the potential for encounter with humans. It is caught regularly in target and nontarget fisheries. (2011). The killer whales then bite off the sharks fins then disembowel and devour them midwater. , The young develop inside the mother's body up to 16 months.

The skin of a tiger shark can typically range from blue to light green with a white or light-yellow underbelly. The Tiger Shark is found in many tropical and temperate waters worldwide. Though apex predators, tiger sharks are sometimes taken by groups of killer whales. In the western Pacific Ocean, the shark has been found as far north as Japan and as far south as New Zealand.  They breed by internal fertilization. The advantage of this is that when it is hunting for its prey, when prey looks at the shark from above, the shark will be camouflaged, since the water below is darker And when prey is below the shark and looks up, of course because of the sun, it is lighter so that the light underbelly will also camouflage the shark.  The tiger shark also dwells in river mouths and other runoff-rich water. While the teeth of other sharks which hunt swimming prey as a rule are designed to cut in the upper jaw region and to grab and hold onto possible prey in the lower jaw, tiger sharks have rows of almost 24 identical teeth both in the upper and lower jaws.

The tiger shark is a solitary, mostly nocturnal hunter. Certain tiger sharks have been recorded at depths just shy of 900 m (3,000 ft), but some sources claim they move into shallow water normally thought to be too shallow for a species of its size. s pattern, but fade as the shark matures. Weights of particularly large female tiger sharks can exceed 900 kg (2,000 lb). Once the shark has come close, a speed burst allows it to reach the intended prey before it can escape.  Its behavior is primarily nomadic, but is guided by warmer currents, and it stays closer to the equator throughout the colder months. Feeding sharks in Hawaii (except for traditional Hawaiian cultural or religious practices) is illegal, and interaction with them, such as cage diving, is discouraged.  The genus, Galeocerdo, is derived from the Greek galeos, which means shark, and kerdo, the word for fox.

A newborn is generally 51 to 76 cm (20 to 30 in) long. Click the button below to add the Tiger Shark Tooth to your wish list.  Typical weight of relatively young sexually mature specimens, which often locally comprise the majority of tiger sharks encountered per game-fishing and scientific studies, is around 80 to 130 kg (180 to 290 lb). They are especially well camouflaged against dark backgrounds. , The tiger shark is considered to be sacred na ʻaumakua (ancestor spirits) by some native Hawaiians, who think their eyeballs have special powers of visual perception.. They are considered a near threatened species due to excessive finning and fishing by humans according to International Union for Conservation of Nature. , Males reach sexual maturity at 2.3 to 2.9 m (7.5 to 9.5 ft) and females at 2.5 to 3.5 m (8.2 to 11.5 ft). Other locations where tiger sharks are seen include off Africa, China, India, Australia, and Indonesia.. Litters range from 10 to 80 pups.

Though apex predators, tiger sharks are sometimes taken as prey by groups of killer whales. , The tiger shark is captured and killed for its fins, flesh, and liver. 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).

The reason for the larger caudal fin on juvenile tiger sharks is theorized to be an adaptation to escape predation by larger predators and to catch quicker-moving prey. However, tiger sharks in Hawaii have been observed in depths as shallow as 3.05 m (10.0 ft) and regularly observed in coastal waters at depths of 6 to 12 m (20 to 40 ft). Each tooth is almost like having several teeth in one space; the sharp, primary cusp extends down, ready to tear into prey.  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. , The tiger shark is second only to the great white in recorded fatal attacks on humans. , Although tiger sharks are apex predators, they are often killed and taken as prey by pods of killer whales.  They also eat other sharks (including adult sandbar sharks (Carcharhinus plumbeus)), as well as rays, and sometimes even other tiger sharks. It also has a reputation as a "garbage eater",consuming a variety of inedible, man-made objects that linger in its stomach.

Like most sharks, its teeth are continually replaced by rows of new teeth throughout the shark's life. In the Southern Hemisphere, mating takes place in November, December, or early January.
