Looks like we found a knobbed pear conch!
I don't know about you, but I've never found anything as large as this on a beach. Usually, I just find tiny shells or broken bits. Ben stumbled across this one sticking out of the sand partially and dug it up with his feet.
We were so surprised to find something so large and beautiful. A little girl next to us exclaimed, "Did you really find that on this beach?!"
The book we have is called A Maxton Book About Sea Shells (Maxton Books for Young People)--I couldn't find a cover image for it. But these golden guides look pretty good, too. I'm partial to the vintage ones.
Do you have a favorite shell guide?
