Sharks are Misunderstood

Sharks are awesome creatures and are often misunderstood. 

I also feel misunderstood, so I got a shark tattoo on my arm.  However, that is not the point of this blog post, so let get back on track.

Here are some interesting facts about sharks.

  1. Sharks don’t have bones, instead they have cartilage.  That is what makes a shark a shark, it’s not about size, shape, or eating preferences.
  2. Sharks have electroreceptor organs and can sense electromagnetic fields.
  3. Shark skin is made of dermal denticles, which is so rough it could be used as sandpaper.
  4. The whale shark can grow up to 40 feet long, but lives on a diet of plankton.
  5. Bull sharks can live in salt and fresh water.
  6. The dwarf lantern shark is about the size of a goldfish.
