American Museum of Natural History

On the first floor, the Hall of Ocean Life lets you dive into the depths of the oceans. You learn how diverse the marine environment is and you can also find the largest animal in the world, a blue whale, right above your head. The blue whale is only one of 750 sea creatures on display here. In the deep blue you might also encounter a sperm whale and a giant squid fighting or a whale shark, the largest living fish.
