Curious facts about great white sharks
Great white sharks are the largest predatory fish on the planet
White sharks have six highly refined senses: smell, hearing, touch, taste, sight and electromagnetism.
Basic facts of the great white shark
Great white sharks are the largest predatory fish on the planet. They can measure more than 20 feet (6 meters) and weigh up to 5,000 pounds (2,268 kilograms).
They are intelligent and very curious creatures. They have senses and an exceptional highly developed brain that coordinates all of them. As a result, they are located at the top of the ocean food chain.
The upper part of its slate gray body mixes with the rocky seabed, and its bellies are always white – that’s where they got their name. Unlike other fish, sharks have cartilaginous skeletons instead of bones.
A great white shark has 300 teeth, and are arranged in up to seven rows.
Great white sharks are designed for speed. Its torpedo-shaped body and powerful tail helps them swim at speeds up to 15 mph (24 kph). When they chase the prey they can push their bodies completely out of the water. His attack strategy involves a quick surprise attack from below before inflicting a powerful and potentially fatal bite.
When they are young the great white sharks feed on fish, rays and other smaller sharks. As they mature, they begin to feed on marine mammals, such as seals, sea lions, and elephant seals, and large corpses adrift. They like the grease-rich tallow coat of dead whales. White sharks are known to attack, but not eat, humans.
Great white sharks usually give birth to between two and 12 babies every two or three years, and gestation lasts at least a year. Unlike other sharks, great whites are born live and can swim immediately. No one has ever witnessed a reliable mating.
White sharks reach maturity around the age of 15 and can live for more than 60 years.
Great white shark facts
Great white sharks live in almost all oceans and seas, although they prefer temperate coastal areas. They can live in the open ocean or near the islands and continental coasts, both in icy and tropical waters, and in depths from the surface to about 820 feet (250 meters). Great white sharks have been tracked swimming from South Africa to Australia, and from California to Hawaii – the longest recorded migrations of any species of fish.
State of conservation
The threats to the great white shark are sport and commercial fishing for its fins (which are used in shark fin soup) and jaws (which are often hunting for trophies); accidental entanglement in protective beach mesh and commercial fishing nets; and the destruction of habitats near the coast, where young sharks are born and grow.
More curiosities about the great white shark
White sharks have six highly refined senses: smell, hearing, touch, taste, sight and electromagnetism …!
Their sense of smell helps them detect substances in minute concentrations – 1 part per 10 billion parts of water. A large white shark can smell a seal colony 2 miles away (3 kilometers).
The pores in this shark’s snout are filled with cells that can sense the electricity and direction of electric currents. They use this sense to navigate the open ocean, as well as the origin of the small electrical signals of the hearts and gills of the prey.
Most of the great attacks of white sharks are not fatal. Researchers believe that these curious sharks are only actually “testing the prey”, then they release their human victims instead of attacking to kill and eat people.
