So I have finally gotten some pictures from Eelco and I thought I'd post them. Hope you don't mind ;)
As you can see from the pictures we start from the top, with the Japanese forest. Then we move on further down, where we can see all kinds of interesting life-forms.
Including some wicked huge fish and crabs. No zoom were used. They were just that big. I would probably fail hard if I were to try to wrestle these things, for the time being ignoring the issue that is lack of oxygen.
You also see the lucky guy who has the job of cleaning the aquarium windows from the inside, in the room where you have stingrays and sharks. Whee :D
Finally, we see the Osaka Aquarium building, from atop the ferris-wheel, me and Eelco decided to try out. It should hopefully be pretty obvious that Osaka is indeed a port-city ;)
