Do all of these really deserve that title? I've never heard of many of them, and while that doesn't inherently mean that aren't world class it does seem a bit suspicious.This is false. I am going to try to list as many aquariums with world-class exhibitry as possible.
Okinawa Churaumi Aquarium
Osaka Aquarium
Monterey Bay Aquarium
Georgia Aquarium
Shedd Aquarium
Aquamarine Fukushina
Lisbon Aquarium
Acuario de Valencia
Two Oceans Aquarium
Numazu Deepsea Aquarium
And this is just within a quick timespan. I'm sure I can list more.
Regardless, I raise you:
Omaha
Wroclaw
Innsbruck
Antwerp
Berlin
Toledo
Köln
Arnhem
Rotterdam
