I want to know the answer to the following question:
What kind of crabs besides hermit crabs are common on the beach in St. Barts?
All the background I'm provided with is that "On the shore are ghost crabs, which always live on the beach in small burrowed tunnels made in sand, and the hermit crabs, which live in land but lay eggs in water and which also eat garbage and sewerage.". Is that enough to answer the question?
