They have been around for more than 450–420 million years, which means they predate dinosaurs! Sharks’ ancestors were some of the first vertebrates on Earth.

The latest research suggests that sharks could be as crucial to our ecosystem as trees or bees. Sharks help maintain healthy fish populations by removing sick and dying individuals from a population before passing on disease or suffering starvation.

‘Sharks’ are the biggest and the most frightening looking of all fish in the sea. The shark has a streamlined body, which enables it to swim effortlessly through the water. It has two powerful tail fins.

These fins are spread out like wings. They make it easier for the shark to swim. The tail also helps the shark steer through rough waters and turn quickly when attacking its prey.

The skin of a shark is covered with small tooth-like scales called “dermal denticles.” They help protect the fish from injury as they move through water because the thin scales do not catch on to things.

The shark has a mouth full of sharp teeth, which the animal uses to attack its prey. Many types of sharks have rows of tiny spikes on their heads called “cephalic lobes.”

The scales help protect them from other large predators like whales and killer whales that eat fish.

Some species, such as hammerheads or angel sharks, have large ‘wings,’ which they use to glide through the water.

The shark has a nose called “the rostrum.” The nostrils are at the top of this nose, and below them, there is a row of teeth that helps catch food as it swims.

A shark’s colour comes from light reflecting off its skin. Depending on the type of light, a shark can appear black or dark grey. They have a white belly.

Sharks are the apex predator of their mostly near-shore habitats. The size and shape vary significantly among 250 different species, with some growing to more than 16 ft (500 cm) and weighing up to 3000 lb (1360 kg).

The most giant and most ancient seaside shark is the megalodon, measuring up to 59 ft (18 m) and weighing over 50 tons.
