 10 Facts About Sharks

  1. There are about 500 known species of sharks, and new ones are still being discovered!
  2. A shark’s skeleton is not made of bone; it’s made of the more flexible cartilage like that found in our noses and ears.
  3. Sharks have several rows of teeth, but they are not anchored in their jaw like other fish, so sharks often lose their teeth, especially when feeding.
  4. Sharks have special pores along their jaws and snouts that help them detect the electrical signals of other sea creatures like stingrays.
  5. Being cold-blooded, sharks have a slow metabolism, meaning they don’t have to eat as often as warm-blooded animals. In fact, some sharks only have to eat once or twice a week.
  6. Sharks can swim very fast, but they can’t stop quickly, nor can they swim backwards.
  7. The skin of a shark feels like sandpaper because it’s made of tiny teeth-like scales.
  8. Ironically, Whale Sharks and Basking Sharks are the largest shark species, but they primarily eat microscopic plankton.
  9. When it comes to mating, female sharks can store the sperm of a male shark for years until the time is right to fertilize the eggs.
  10. Baby sharks are called pups, and they are fully independent from the time they are born.
