Looking through all the Facebook pictures many of my friends spent their holiday outside. We were no exception, well the kids and I. Poor Shane was working. We, of course went to the beach! While we were there Aspen looked for shells, I looked for shark's teeth and Matthew brought me garbage. Both of my kids can't walk by a piece of garbage on the beach. If they see trash they pick it up and throw it away. We usually go to the state park because there is less garbage and they can enjoy themselves more.
We found four shark's teeth at the beach today. I finally googled "why are shark's teeth black" and learned something new! I learned in Florida every spring there is a Shark's Tooth Festival. The festival even has a 10k for you runners out there! When we find shark's teeth on the beach they are usually black. I learned this is because when the tooth falls out of the shark's mouth and settles on the ocean floor it becomes the color of the sediment. The minerals in the sediment replace the dentin and enamel that makes up the tooth, then the tooth turns that color. Off our coast that is black. I did not know there are other colors of shark's teeth. Interesting!
