Sand fiddler crabs have home advantage in competition for breeding burrows

One study showed that if their claw strength is similar to that of a competing crab, sand crabs living in caves are often challenged by another crab.

In a paper published in the Springer Journal of Behavioral Ecology and Social Biology, the characteristics of sand-sand crabs that determine the outcome of competition between invaders and breeding cave dwellers are identified. Dr. Denson McLain of the Southern University of Georgia in the United States and colleagues found that when a resident
