According to the Natural History Museum, sharks can be traced back to 195 million years ago. The shark belongs to the superorder Selachimorpha and sharks are found in almost every ocean of the world. Sharks commonly don't live in freshwater, but a few shark species (like bull sharks and river sharks) can swim in both freshwater and seawater. All sharks can go deep in the ocean up to 7000 ft (2.1 km), while some shark species live deeper under the oceans, at around 10,000 ft (3 km). The Portuguese dogfish shark is recorded as going deep under the ocean at 12,100 ft (3.7 km)!

There are around 470 different shark species and it is believed that there are many more species of sharks that are still unknown. The biological name of a bull shark is Carcharhinus leucas, and this species can have a lifespan of up to 16 years. Female bull sharks are bigger in length than male bull sharks and they can swim up to 12 mph (19 kmph). The scientific name of the Greenland shark is Somniosus microcephalus. These are true sub-Arctic sharks who live in the cold waters of the North Atlantic around Iceland, Greenland, and Canada. They choose cold waters of between -1 C and 10 C, and in summer when there is warm weather, they go deeper into the water to find a colder environment. They can eat almost anything, and these marine creatures can live for 200 years, according to scientists! Their swimming speed is very slow at 0.98 ft/s (0.3 m/s). No one can consume the meat of this particular shark species as it contains a very high level of urea, which has a urine-like odor.

A shark's skin is made up of tiny teeth-like structures called placoid scales. Because of this, their skin feels like sandpaper to touch. They have around 30000 teeth and each species has a different teeth structure. Mako has pointed teeth, whereas white sharks have triangular, serrated teeth. A sandbar shark will have around 35,000 teeth over the course of its lifespan. They also have strong jaws which help them eat tough and hard materials.

According to the IUCN, sharks are at risk of becoming endangered. An unfathomably large number of them are killed due to overfishing and the growing demand for their fins. Overfishing is not only the reason behind this decline in their population though, another reason is climate change. Only a few sharks like freshwater, and most of them like seawater, but the water's changing temperature has left many sharks struggling to survive in recent years and seawater has become an uncomfortable place for them to live.

Did you know...

Nearly 100 million sharks disappear every year, and most of us are unaware of this fact. This amazing creature from marine life is at risk from overfishing by humans, so much so that some species of sharks are listed as Endangered by the International Union for Conservation of Nature.

Reef sharks are considered the most important part of marine life. There are five types of reef sharks: blacktip reef sharks, gray reef sharks, Caribbean reef sharks, whitetip reef sharks, and the silvertip reef shark, found in the Indian and Pacific oceans as well as the Mediterranean Sea. They can't go deeper than 260 ft (79 m) in water, prey on crab, lobster, shrimp, and squid, and are viviparous by nature.

Mako Sharks are well-known as 'bonitos' and 'blue pointers'. These creatures are large sharks and measure up to 10 ft (3m). Mako sharks are warm-blooded and are a close relative of great white sharks. They are oophagous in nature and have a swimming speed of 21 mph (33 kmph).

Hammerhead sharks are from the Sphyrnidae family. These sharks mate once a year and can give birth to 20-40 pups at a time. The bonnethead is a species of hammerhead shark that is omnivorous in nature, and they feed on seagrass. They are at risk of becoming endangered due to overfishing and the demand for their fins. The scalloped hammerhead is another species of hammerhead shark that is a coastal pelagic species and is viviparous by nature. The population of scalloped hammerhead sharks has decreased by 95% in the last 30 years in the Atlantic Ocean.

The scientific name of a whale shark is Rhincodon typus. Whale sharks can grow up to 40 ft (12.2 m) in length and whale sharks are not at all related to whales. Each whale shark has its own unique pattern of spots, much like human fingerprints. Their skin is incredibly tough, it is covered in hard, tooth-like scales, which are called denticles and they are ovoviviparous in nature.

The largest fish predator. the great white shark is 15 ft (4.6 m) in length. The great white shark gets its name from its color, which is gray with a white underbelly. The great white shark can swim at speeds of up to 37 mph (60 kmph). They have a set of 300 sharp, triangular teeth and they use their gills for taking in oxygen.

Sharks can fossilize even though they don't have bones and, interestingly, the dried jaws of a shark are heavy and solid, much like bones.

Many of these species have amazing eyesight, they have a reflective layer of tissue called a tapetum behind the eyeballs, which helps the shark to see clearly even in dim light. Also, sharks have electroreceptor organs that help them to sense electromagnetic fields and temperature shifts in the water.

Do sharks attack humans?

Sharks don't attack people often. If a shark does attack a human, it's generally an instance of confusion  in the water.

What are sharks afraid of?

Sharks are afraid of their predators. For example, great white sharks are afraid of killer whales. Orcas can also kill sharks by working together. Sharks can also be terrified of dolphins if there are a lot of them in one territory.
