Birch Aquarium - Shark - as part of the expert series by GeoBeats. Another of our most popular species is, of course, the shark. Everybody knows about sharks from the movie Jaws and Shark Week, but sharks are really misunderstood animals that have a lot to be afraid of from us. There are very, very few shark attacks every year and usually that is just a case of mistaken identity, whereas we kill 300 million sharks a year for their fins. And so it is really important when visitors come to Birch Aquarium at Scripps that we get to teach them about these amazing animals. Sharks can live up to 100 years. There are 300 species of sharks and they have been around for hundreds of millions of years. They are incredible survivors. And just looking at sharks in the water, they are beautiful aerodynamic animals that just take your breath away.
