After feeding my sea animals today, I noticed a moon snail crawling out of the sand and up the side of its home. When I placed a piece of clam near it, I was able to see its radula, which is a tongue-like structure with small white teeth that’s capable of scraping a hole right through a clam shell in order to eat the soft body inside. In the video above, you can see the moon snail’s radula and teeth, as it gets ready to stretch it’s tongue out to break off a piece of clam to eat. And by the way, this is the subject of my latest illustrated children’s book, “Did You Make the Hole in the Shell in the Sea?” which solves the mystery of why you can find perfectly drilled holes in shells at the beach. We are looking forward to this book’s release this Fall, 2013.
