Copepods, specifically Pandarus rhincodonicus, often live on the lips and fins of whale sharks, feeding on bacteria and other micro-organisms found on the skin. Because the mouth of copepods can move back and forth, they can also rid sharks of any irregularities found on the skin. Occasionally whale sharks are hosts to remora.
