The zebra shark is a docile, slow-moving shark, considered harmless to humans. It spends most of its day resting on the ocean bottom, becoming more active at night, when it feeds on a variety of bottom-dwelling invertebrates. The species gets its name from the coloration of its young. Newly hatched zebra sharks are dark with lighter, yellowish bars, resembling the stripes of a zebra. As the shark matures, these bars begin to break up into the adult coloration. Mature adults are light tan in color with a dark spotted pattern along the sides and back – leading to one of its other common names – the leopard shark.
