The strangest creatures on the planet, strange and unknown beings, a 13-meter giant squid. The exhibition ' Abissi, terra aliena ' is the new exhibition scheduled at the Aquarium in the purple entrance. The marine ecosystem is the largest environment on earth. In the oceans, sunlight only penetrates up to 200 meters. Proceeding downwards, the water temperature tends to decrease. The deep sea is therefore an extreme environment, inhabited by a few still unknown organisms. With this exhibition we try to make known the wonders and incredible life forms of the deepest abysses . These species are shaped by pressure from absolute darkness and deep frost, have incredible shapes, seem to belong to an alien and imaginary world .
