Tokyo Sea Life Park's most important aim is reproducing aquatic habitats in Tokyo and across the world. In this light, they installed a huge donut-shaped tank (2,200t), where bluefin tunas swim around freely.
Fish and invertebrates are not the only life forms that inhabit the sea. At the aquarium, you can also see penguins, auks, and puffins, typical sea birds which adapt well to marine habitats.
The Seas of the World, Life of the Deep Sea, Life on the Shoreline, the Sea of Tokyo, and Life in Freshwater are some of the exhibit sections. They also collect marine life from the Arctic and Antarctic Oceans..
