Tiger Shark

The tiger shark, also known as a man-eater shark and spotted shark, is a warm, saltwater fish living in various areas throughout the world.

This is the only member of the Galeocerdo genus. It is known for the vertical dark stripes on its back and the fact that it eats many types of prey. It’s hunted by humans for its fins, cartilage, and oil.

5 Incredible Tiger Shark Facts

• A large litter: A female can have from 10 to 82 babies in one litter. Not surprisingly, she only has one litter of babies every three years.
• Speedy hunters: Though tiger sharks are fish that move slowly through the water most of the time, they use quick bursts of speed to capture prey. They can swim at a speed of around 20mph.
• Few predators: Killer whales and humans are their only predators. They are sometimes caught in commercial fishermen’s nets either deliberately or by accident.
• Garbage fish: Tiger sharks are sometimes referred to as garbage fish because they swallow a lot of items besides their prey. Plastic, empty cans, and license plates are just some of the items found in a tiger shark’s stomach.
• Powerful teeth: A tiger shark’s teeth are so strong and powerful that they can bite through a sea turtle’s shell or a clam.

Classification and Scientific Name

The scientific name of the tiger shark is Galeocerdo cuvier. Galeocerdo cuvier comes from the Greek words Galeus (shark) and cerdo (fox). This relates to the sneaky way it approaches its prey. It’s also known as the maneater, leopard, and spotted shark. It belongs to the Carcharhinidae family, which contains 60 species. Its class is Chondrichthyes.

It belongs to the order Carcharhiniformes along with 270 other species of sharks, including the Blacktip Reef Shark, Bull Shark, and Gray Reef Shark, among many others. However, this species is the only member of the genus, Galeocerdo.

Evolution and Origins

The tiger shark’s origin was formerly thought to have occurred around 5.3 million years ago. Nonetheless, scientists were able to locate several 13.8 million-year-old fossil shark teeth, proving that they existed considerably earlier than previously thought.

The majority of scientists think sharks first appeared 400 million years ago. Before the dinosaurs, by 200 million years! They are said to have originated from a tiny fish with the shape of a leaf that lacked eyes, fins, and bones. Eventually, these fish evolved into the two major families of fish that exist today.

While fishing for swordfish in the southern Mediterranean, people unexpectedly snagged one male and one female Galeocerdo cuvier tiger shark specimen. This discovery proves beyond a shadow of a doubt that the tiger shark was found in the Mediterranean Sea’s waters at some point during their evolution.

Appearance

A tiger shark is a fish with smooth, gray skin, a white underside, and dark gray or black vertical stripes on its back. Its nose is rounded and broad. The teeth are curved toward the inside of its mouth. In addition, each of its teeth has a serrated edge. The design of their teeth helps them to bite through shells and the other hard exteriors of prey.

These sharks range from 10 to 14 feet in length. Their weight range is from 850 to 1,400 lbs. The longest tiger shark measured 24.6 feet, while the heaviest weighed in at 1,780 lbs.

Its gray color helps it to blend into the murky water. Not surprisingly, this can also help a tiger shark to sneak up on prey swimming in the same area.

Tiger Shark Stripes

One of the most notable features is the stripes on its back. As it grows older, its stripes begin to fade.

Distribution, Population, and Habitat

The tiger shark lives in tropical waters in many places throughout the world. They are saltwater fish that have been seen around the central Pacific islands, in the Gulf of Mexico off North America, and the Caribbean Sea. They have been seen off the coast of South America, China, Australia, Indonesia, Africa, and India. Though this shark spends time swimming near the surface, it normally swims at a depth of around 460 feet.

These sharks migrate with the change of seasons. When the weather turns cold, they move from temperate waters to tropical waters. Alternatively, when the warm weather returns, they move from a tropical habitat to a temperate one.

There is a lack of data regarding the population of this creature. However, the official conservation status is Near Threatened. Its numbers are decreasing due to poaching. They are hunted for their fins, their skin, and the oil contained in their liver. They are often caught in commercial fishing nets.

Predators and Prey

Killer whales and humans are both predators of adult tiger sharks. Killer whales are larger in size and weight than tiger sharks, allowing them to overwhelm these fish. Humans capture baby and adult tiger sharks in commercial fishing nets and kill them for their skin, liver oil, and cartilage.

Baby tiger sharks are sometimes as small as 20 inches long at birth. This makes them vulnerable to being eaten by larger sharks and seals.

A tiger shark has a long list of prey. Some of the things these sharks hunt include squid, sea turtles, dolphins, smaller sharks, clams, rays, and seabirds. This shark will swallow things it finds in the ocean, including plastic, license plates, and anything that looks tasty! They hunt at night, which means they are even harder to see in the murky water.

Reproduction and Lifespan

In the northern hemisphere, the breeding season of this shark goes from March to May, while the breeding season in the southern hemisphere goes from November through the beginning of January. After the male mates with the female, the babies develop in eggs inside the mother. After a 13- to 16-month gestation period, the female gives live birth. She can have from 10 to 80 babies or pups. A female tiger shark has a litter of pups just once every three years.

Shark pups can be from 20 to 30 inches in size at birth. Each baby leaves its mother right away to live independently. These sharks reach sexual maturity at about 7 to 10 years old. Tiger sharks live to be about 15 years old, but it seems they can live a lot longer — the oldest tiger shark on record was 50 years old.

Fishing and Cooking

Tiger sharks are sometimes caught in commercial fishing nets by accident and sometimes deliberately. Either way, tiger sharks are usually killed for their skin, fins, cartilage, and the oil in their liver. The number that is caught in commercial fishing nets is not known.

This shark is not one that many humans eat. Its meat has a strange taste. Plus, this fish ingests lots of different items, both edible and non-edible. This makes them even less appetizing.
