Despite the fact that most sharks are harmless, still just a thought of single shark makes some people nervous and scared. Sharks are big beasts of the seas that look very dangerous. They are also very intelligent creatures and there is still so much mystery about the sharks. Over 500 types of sharks are floating in the seas in the world and thousands species of sharks that come and go over the course of millions of years. All types of sharks are an integral part of our world’s aquatic ecosystems and sharks worth all attention and protection we give. From all species of sharks, only 40-50 are known to attack people and so they earned their nickname – scary sharks. Sharks are located all across the world, but today we take a closer look at the top 5 types of sharks due to their uniqueness, appearance and ability.
The White Shark is known as the most dangerous shark in the Ocean, but still it attacks extremely rare even if you swim in close proximity. This shark specie is responsible for 403 attacks from 1580-2010; 180 of these were unprovoked and of these, 65 were fatal. A shark of this specie looks very powerful, scary with exceptional speed and maneuverability. We can surely say that the Great White Shark is the king among all sharks, because is one of the oldest and most adaptable creatures on the Earth. Their size is about 10-15 feet long on average and can weigh up to 4,200 pounds that makes it easily recognizable, but you can also recognize a White Shark by their steel gray back and white underside, and large black eyes. The White Sharks are known by their exceptional swimming abilities heightened with their powerful tails and can propel through the water with speed of 24 km\h. They are also very known by their incredible jumping skills.
Named by their unusual rectangular structure of their heads, the Hammerhead Sharks are very unique creatures that belong to Sphyrnidae family. The specie “Hammerhead Sharks” has 9 different species and the largest is the Great Hammerhead Shark who can grow 6 meters long and can weigh 170 kilograms. Of the 9 known species of Hammerhead, three of them can attack people. This specie is interesting because of their eyes placed on the outer edges of the hammer that allows them a vertical 360 degree view. Their heads can help them to find food and make turns sharply without losing stability (well-known for sharp and sudden turns). Another interesting thing at these sharks is that they can get nice tan – the only fish that tan from the sun. They inhabit tropical and warm temperate oceans around the world.
Tiger Sharks have that name from the tiger like stripes and spots that can be seen on their side which fade away as they get older. They are known as likely to attack as they are responsible for 157 attacks, 63 of these were unprovoked and of these, 27 were fatal. Tiger Sharks eat everything, although their preferred prey includes sea turtles, rays, fishes, sea birds, squid etc. and that’s the reason why are they often called “The Wastebasket of the Sea”. Galeocerdo Cuvier is their other name and can be found mostly in tropical and warm waters. They can grow up to 15-16 feet long and can weigh around 1,800 pounds. They prefer hunting in darkness and enjoy visiting areas often used by humans and they are top prize on many contests. Nowadays, the Tiger Sharks are considered as high treat level due to the hunting by humans and lately, they have been put on the Marine red list that makes them illegal to fish or hunt across the world.
The Whale Shark or Rhincodon typus, is a huge shark that it’s only a whale by length and it’s the largest fish in the Ocean. It is very slow moving filter feeding shark that can grow up to 40 feet long and can weigh up to 15 short tons. Basically, the Whale Sharks swim through the water and use their immense gills as a filter that captures plankton and vegetation as it swims. They can be found in warm and tropical Oceans, and can live about 80 years. Their back is gray, brown or blue in color, covered with regularly arranged light spots. The Whale Shark specie dates about 60 million years ago and they are the most visited sharks because they are very gentle and harmless. Shark divers and snorkelers can even swim or play with this fish with no risk.
The Bull Shark, one of the most dangerous sharks, is often on the top of many lists. We are talking about a large shark that is responsible for many unprovoked attacks on humans, less than 4.5 deaths per year globally. The Bull Sharks have blunt snout, a gray back and light underside and can grow up to 11 feet long and weigh 500 pounds. Their name in the scientific community is Carcharhinus Leucas, a shark with stocky figure and a broad, flat snout. They are one of the few species sharks that can live in both fresh water and sea water and this fact alone makes this specie one of the best. The only consequence is they produce 20 times more urine when swimming in fresh water.
