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 "The marine life found here consists of anemones, urchins, sea cucumbers, and eels, which all live on the reefs along with turtles, conch and many varieties of marine fishes.". Is that enough to answer the question?
