At the end of the alley is famous Lisbon Oceanarium. It is raised a lot of different marine fish. There are huge, and there are small fish. The most interesting fish that I saw there was a fish-moon. This is a great size for your fish, whose fins are stacked up, and the other down. It actually looks like the moon, as well as approximately circular in shape and very thin. Size of fish was about 3 meters and weight seems a half tons. No wonder she is the pride of the Oceanarium.
