Just ran across this cool photo of a hermit crab that had made a home in a fossil Chicoreus shell in Curacao. It’s from Barry B. Brown’s Coral Reef Photos blog. I’m assuming it is probably a specimen of Chicoreus (s.s.) brevifrons. I have many fossil muricids in my collection that show evidence of ancient hermit crab habitation, indicating that crabs have had excellent taste in personal shell collecting for a very long time! 🙂
Here’s some more info on the fossil shells of Curacao from the same blog.
