On the east side of Meeru, lived many hermit crabs. They did not take up the entire beach, but a section in between the Adult Pool and the beach bungalows.
If you find a hermit crab, leave it in its shell. They live in empty shells until they outgrow them. Then, they move onto bigger shells.
If you accidentally bring one home, take the shell to the beach. The hermit crab should survive then at its best.
Sometimes an animal you do not expect, ends up being the most fun!
