Mysteries of the Sea

The new “Mysteries of the Sea” exhibition is made up of six aquariums called jewels, due to their smaller size and extraordinary content.

In Mysteries of the Sea, you can observe animals which are amazing due to their beauty, unusual shapes and astonishing characteristics. The tanks are surrounded by large figures representing some of the largest creatures of the ocean depths and other smaller creatures. In the jewel aquariums, specimens of 16 species can be observed, such as the peacock mantis shrimp, the yellow boxfish and the longhorn cowfish.
