This rescued elephant roams around freely all day, but when the evening comes, it goes to its pen for safety, where it gets some nice hay and pellets. It is amazing how such a big animal is able to pick up such small things from the ground, but he picks up his pellets with ease, using his trunk as fingers. An elephant's trunk is a prehensile elongation of its nose and upper lip, making the tip "finger-like". It is formed by over 40,000 muscles split into thousands of individual units, making it so strong that an elephant can lift about 3% of its body weight with it. It innervated primarily by the trigeminal nerve and used for picking things up, feeding, touching, drinking, dusting, making sounds, socializing, threatening, fighting, smelling, and breathing both while on land and while swimming, kept out of the water, as a snorkel.
