On a recent trip to Florida while beachcombing I began collecting sharks teeth. I had remembered seeing the postcards with the different types of shark’s teeth on them. The picture showed sharks teeth in several different shapes and in both black and white. After finding several dozen black sharks teeth my mission became to find a white sharks tooth.
Even after hunting for several hours I failed at my mission. I began to wonder why? Why were black teeth so prevalent and white teeth were so hard to find?
It was time to do some research about sharks teeth. Thank heavens for Google!
I learned that all sharks’ teeth start white. They are white in living sharks.
The teeth are made up of calcium phosphate. When the tooth falls out it begins to absorb the sediments in its surroundings thus causing the color change usually tan, brown or more commonly black.
Since I didn’t come across any living sharks, and since I wasn’t planning to extract their teeth if I did find one I never did get a white sharks tooth. I guess my white shark’s tooth collection will be extremely small!
But I did learn something new on my adventure. Oh and FYI if you are buying shark’s teeth in local souvenir shops remember those white sharks teeth are either replicas or were ripped out of a live or recently killed shark!! Please help save these amazingly interesting animals.
