Shark Week July 11-18, 2023

Let’s take the time to learn more about these unique ocean creatures. Kids and adults, too, have always been fascinated by sharks. I am sure some of it concerns the movie Jaws and what we read about attacks. However, there is so much more to sharks than attacks!

There are many species of sharks, and you might even be surprised that the biggest shark is often called a gentle giant. Make shark week an educational week full of learning about these marine animals. Check out AZ Animals to learn more about the history behind shark week.
