A diver amongst the fish
To ensure that the species evolve in a healthy environment and so that you can watch them undisturbed, the handlers look after the installations from inside the aquariums.
During this stage of Nausicaa's life, the divers have the opportunity to scour the tanks, and often find some surprising things to show you... such as shark teeth, for example!
The "Diving in Malpelo" activity is included with your ticket.
Just turn up at the Giant viewing panel - space n° 12 in the "Journey on the high seas" tour - at the time indicated in the schedule of activities.
