How did the Elephant Skin get its Cracks? New Research Has an Answer

An intricate web of cracks adorns the wrinkly, gray skin of Africa’s bush elephants. The tiny crevices hold water, which helps keep the animals cool and prevents dehydration in their dry habitat. Now, scientists have figured out how the channels on African elephants’ skin form — the outermost layer of skin gets thicker and bends until the brittle material fractures from the strain. The discovery may provide insight to a common genetic disorder in humans.Cracked Crocs
