Sharks are incredible creatures, but they are experiencing a serious decline in their population due to the harvest of shark cartilage for bogus supplements and due to shark finning for soup.  Check out these 10 facts and infographic below to learn all about sharks:

  1. Modern sharks have been around for 100 million years, but their ancestors are as old as 400 million years.
  2. Sharks have 40 to 50 teeth… in the front row.  New teeth are lined up behind them.  And a shark may go through as many as 30,000 teeth in it’s lifetime.
  3. The Whale Shark can live up to 100 years of age.  It’s also the largest shark species.
  4. Research has helped bust the myth that sharks are attracted to the color yellow.  The expression “yum yum yellow” was rooted in the idea that sharks could see and were more likely to approach divers wearing the color. Because sharks’ eyes were found to lack or have minimal color-sensing cells , it seems to make more sense that what actually draws attention is the contrast in colors, rather than the color itself.
  5. Sharks DO get cancer.  The myth that they do not has lead to a shark cartilage economy.
  6. There’s little to no evidence to support that shark cartilage has any advantage for humans wishing to stave off cancer or to improve the health of their joints.
  7. Shark fin soup accounts for roughly 100 million shark deaths each year.
  8. More than 100 species of sharks are being commercially exploited.
  9. Since 1580, there’s been only 486 shark deaths.  That’s an average of one per year.
  10. Hippos, crocodiles, elephants, lions, and jellyfish account for many thousands of deaths each year… tack on snakes, scorpions, bees, and mosquitoes, and sharks account for a completely insignificant number of deaths.
