(PHYSorg.com Biology)

When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances-overcrowded conditions, not enough food-by completely remodeling their bodies. These stress-induced forms, whether they offer a protective covering or more camouflaged coloration, can better withstand the challenge and help the animal survive until conditions improve.
