A land crab investigates falling fruit
Cardisoma guanhumi lives along Atlantic coastal regions of the Americas and eats leaves, fruit and other foods. Experiments show that falling-fruit sounds can draw it from its burrow to search for food. Before moulting, it can seal the burrow entrance with mud.
A sound invites a meal; mud closes the door for a moult.
