7 Interesting And Fun Facts About Sharks
Sharks never cease to amaze humans. That’s why here we are enlisting the top 7 interesting facts about them which will not only increase your knowledge but will keep you hooked on sharks forever.
1: Sharks have 2 sets of teeth – functional teeth or growing teeth which are arranged in multiple rows. When the functional teeth fall off, the growing teeth from the back row move forward to fill the vacant space. On average, sharks produce 35,000 to 50,000 teeth in their lifetime.
2: All sharks vary in size – the Whale shark is the largest species of shark’s epoch with an average length of 40 feet whereas the Dwarf Lantern shark is the smallest species that can reach up to 6 to 7 inches in length.
3: The large sharks have a remarkable life span; it is recorded that Whale sharks can have an average life span of 70 years but some studies suggested that they can even live for 100 years as well.
4: Like fishes, sharks are cold-blooded animals that are unable to regulate body temperature with their surroundings. Interestingly, some species of sharks such as The Great White shark are warm-blooded animals – they can regulate their body temperature. The uniqueness of White sharks allows them to swim faster while hunting.
5: Sharks have always been portrayed as fearsome creatures which is why it is believed that they may attack humans for food. But that’s not true, sharks do not attack humans for food. However, they attack people only out of curiosity, or mistaken identity but once they understand the circumstances, they will set you free. How humble they are!
6: Because of their heavy bulky body and large size, people believe that sharks require tonnes of food every day to keep their energy level high. But you will be surprised to know that sharks eat twice or thrice a week. They have a slow metabolic rate which is why they first digest the previous meal and feed only when they feel very hungry.
7: About 100 million species of sharks have been slaughtered by humans for fins, oil, and meat all over the world. Out of 500 species, 201 are recorded as endangered species on the red list of IUCN only because of the overexploitation of one of the most important creatures of the ocean – the sharks.
There are more than 500 species of sharks living in the open waters, some species frequently visit the shorelines which is why they are easily spotted by visitors. However, few species prefer to live deep in the ocean and are rarely seen near the shoreline. These sharks are named Cool sharks including Bull sharks, Six gills’ sharks, Epaulette sharks, spinner sharks, and many more.
