harks, the apex predators of the oceans.
Many people fear them for their reputations as gigantic man-eating predators, but not all sharks are man-eaters. In fact, not all sharks look like the image we have in our heads.
Here are a few interesting facts about sharks.
1. There’s a massive size difference between the largest and smallest sharks
The largest shark is the whale shark, which, at 46 feet is the size of a school bus. Oh, and don’t be afraid the whale shark’s gonna come for you like the titular villain from Jaws. They’re filter feeders, and only eat plankton and fish.
The smallest shark is the dwarf lanternshark, which, at 7.9 inches, can fit in the palm of your hand. Dwarf lanternsharks eat krill, tiny crustaceans and small fish.
2. Sharks are very different from other types of fish
They belong to a class of fish called Chondrichthyes – that is, cartilaginous fish. Sharks and other Chondrichthyes – rays and skates – have cartilage instead of bone skeletons.
Cartilage, by the way, is the bendy stuff that shapes your ears. It’s also what your nose is made of.
3. Sharks have a very, very acute sense of smell
Have you ever heard the saying “sharks can smell a drop of blood from a mile away?” Well that one’s actually false.
