1) Many animals migrate to find food, breeding grounds, or a better climate. Whale sharks migrate long distances to seasonal feeding locations and travel between Australia and the Pacific Ocean. 2) The humpback whale migrates up to 5,000 miles between breeding grounds and feeding areas, while the monarch butterfly travels 2,000 miles between Canada and Mexico for climate. Salmon return to their birth rivers to breed. 3) The whale shark is the largest fish, reaching 46 feet. They eat plankton and small fish and prefer warm water temperatures. Their spots help them blend in.
