#4 Whale Shark (61.68 Feet)

Meet the magnificent whale shark, the largest fish in the ocean. These beautiful animals cruise the world’s oceans in search of plankton and participate in other fish-like behaviors, occasionally even engaging in play with those who like swimming with them.

If you see a whale shark, you probably won’t miss this friendly creature because it is 60 feet long. The unique light and black markings on the shark should get your attention if its size doesn’t. These fish, which resemble whales more than sharks, are categorized as endangered because they are still being fished in some regions of the world.
