Contrary to popular belief, sharks do not like to eat humans.
The name shark is derived from the Dutch word schurk which means villain. Opposite to its name, sharks are not really our villains. Being practical feeders, sharks commonly feed on smaller fish and weaklings. These fanged creatures only attack humans when they are confused or curious.
Sharks have been on Earth’s water for more than 400 million years.
Sharks have be on Earth’s water for over 400 million years which only means that they have been swimming the waters long before dinosaurs were evening walking Earth. There are over 1,000 species of sharks in the world and new ones are still being discovered each year. And majority of them can live up to 20 to a whopping 150 years of age!
Pearly whites for life.
Sharks loose teeth whenever they take a bite. But they have nothing to worry about because they have a never-ending supply of teeth. Whenever they lose one, another one grows out by the next day. Even baby sharks are born with a full set of teeth.
Sharks’ teeth are not attached to its jaw bone like us humans. Theirs is attached to the soft tissue of their gums. And it is said that they lose about 30,000 or more teeth a year. Can you imagine how many teeth you’ll find on a seabed?
Another shocking fact we discovered is that sharks have no bones. That’s right! Their skeletons aren’t made out of bones but by cartilage(firm and elastic tissue that covers and protects the ends of long bones at the joints) and pure muscle.
The cartilage behaves like a rubber band where you can bend it any way! Now, we know why sharks are so flexible in their movements.
Less noise, more action!
Sharks are silent killers because they have no vocal chords but they do express themselves physically. For example, Hammerhead Sharks do reverse flips and full twists and stalk their preys until they’re tired and scared. Then it’s meal time!
Even their sense of smell is dangerously accurate as they can smell blood miles away. Whichever nostril catches the scent of blood, is the direction the shark will swim towards. And you can be sure, it will swim at top speed in order not to miss out on the feast!
That’s all we have for today. It’s always fun to learn more! Remember - it’s all animals, all the time!
