This is the largest fish in the ocean. Its eyeballs are covered in teeth. The whale shark, up to 18 meters long, larger than a school bus. Every inch of its body carries a pattern of spots. No two whale sharks share the same one. It stays exactly the same for life, like a fingerprint. It filters over 600,000 liters of water every hour. Its throat is the size of a softball. The largest fish alive survives on some of the smallest food in the ocean. It has no eyelids. Tiny tooth-like scales cover each eye and it pulls the whole eye backward into its skull for protection. Even its eyes wear armor.
