Colossal crabs may hold clue to Amelia Earhart fate

"During the day, when the scientists do most of their work on the Pacific atoll, the crabs are easily avoided. Those that emerge from their burrows into the intense tropical heat spend their time in the shade of the coconut palms, say, or among the branches of the ren trees. (Yes, the crabs can climb.)

But at night? “The crabs close in on you,” says John Clauss, a member of the International Group for Historic Aircraft Recovery (TIGHAR) and a veteran of more than ten of the organization’s expeditions to the island. “If you shine a flashlight, outside the shadow ring there are a thousand crabs.” Or so it can seem. Clauss has learned not to sleep on the ground."
