Another beach find from St. Augustine, Florida. What is it?
Answer:
This is a Sand Collar, a cluster of eggs laid by a Moon Snail. The snail surrounds itself with a layer of gelatinous mucous, which contains thousands of eggs. The shape of the Sand Collar tells you how large the snail was. When they are freshly laid, they are very rubbery, but when they dry, they crumble into sand.
