Genoa's Aquarium, one of the largest and most modern marine parks in Europe and one of the most frequently visited tourist attractions of our country, houses fifty-nine tanks that reproduce evocative Mediterranean and oceanic habitats, as well as Polar and Tropical ones, so as to allow over 500 marine species to survive and reproduce. Extraordinary exhibits allow one to view the secret habits of dolphins, sharks, fish of all kinds, penguins, jellyfish, crocodiles, the mysterious, colorful inhabitants of the Caribbean and Red Sea coral reefs. Moreover, a raised walkway leads to the world of seals. Special attention has been paid to educational activities and guided tours are offered for all grade schools. The staff's scientific expertise is constantly being updated through research projects, affiliations, and debates with major Italian and international universities, and with the most important worldwide research centers on marine life and habitats. Every six months a new subject is presented and exhibits and conferences on the topic are organized.
