Why elephants have cracks in their skin
Elephants' wrinkles aren't just about age. In fact, the observation that baby elephants don't have wrinkles in their skin led researchers to wonder why and how these form.
What they discovered is that the skin "cracks" to improve their quality of life, according to a study published Tuesday in the journal Nature Communications.
Researchers at the University of Geneva and the Swiss Institute of Bioinformatics studied the skin surface of African bush elephants and realized that those wrinkles form an intricate network of tiny crevices.
