TOP DANGEROUS SHARKS

1. Megalodon Shark


Megalodon, meaning "big tooth",is an extict species of shark that lived approximately 28 to 1.5 million years ago, during the  Cenozioc Era.
Weight about 100 tonnes.
Jaw weight about 18 tonnes.It eats a human like a human eats a grape.

 

 

2. Bullshark



The bull shark (Carcharhinus leucas), also known as the Zambezi shark or, unofficially, as Zambi in Africa and Nicaragua shark in Nicaragua, is a shark commonly found worldwide in warm, shallow waters along coasts and in rivers. The bull shark is known for its aggressive nature, predilection for warm shallow water, and presence in brackish and freshwater systems including estuaries and rivers.
Bull sharks can thrive in both saltwater and freshwater and can travel far up rivers.
Bull sharks are not true freshwater sharks, despite their ability to survive in freshwater habitats.

 The great white shark, also known as the great white, white pointer, white shark, or white death, is a species of large lamniform shark which can be found in the coastal surface waters of all the major oceans.
It is mainly known for its size.
This shark reaches its maturity around 15 years of age and was previously believed to have a life span of over 30 years. The true lifespan of great white sharks is estimated to be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known. Great white sharks can accelerate to speeds that exceed 56 km/h (35 mph).

4. Tiger Shark

 The tiger shark, Galeocerdo cuvier, is a species of requiem shark and the only member of the genus Galeocerdo. Commonly known as sea tiger, the tiger shark is a relatively large macropredator, capable of attaining a length of over 5 m (16 ft). It is found in many tropical and temperate waters, and it is especially common around central Pacific islands. Its name derives from the dark stripes down its body which resemble a tiger's pattern, which fade as the shark matures.

The tiger shark is a solitary, mostly nocturnal hunter. Its diet includes a wide variety of prey, ranging from crustaceans, fish, seals, birds, squid, turtles, and sea snakes to dolphins and even other smaller sharks. Due to its tendency to swallow virtually anything it encounters, including inedible manmade objects that linger in its stomach, the tiger shark has been nicknamed "the garbage can of the sea". The tiger shark is considered a near threatened species due to finning and fishing by humans.

5. Ocean White Tip Shark


The oceanic whitetip shark (Carcharhinus longimanus) is a large pelagic sharks inhabiting tropical and warm temperate seas. Its stocky body is most notable for its long, white-tipped, rounded fins.

This aggressive but slow-moving fish dominates feeding frenzies, and is a danger to shipwreck or air crash survivors. Recent studies show steeply declining populations because its large fins are highly valued as the chief ingredient of shark fin soup and, as with other shark species, the whitetip faces mounting fishing pressure throughout its range.
