Okay, I don't know if this is AS HOT as Im thinking in my mind, but, I personally think that the Monterey Bay Aquarium Is better than the Georgia Aquarium.
GRANTED, I'VE NEVER BEEN TO GEORGIA (although I really want to) but, I think that what Monterey has put on display far excels Georgia. Sure the Whale Sharks and Manta Ray's are extremely cool, but Blue & Yellow Fin Tuna, Sun Fish, a Kelp Forrest Display that has Live Kelp, one of the biggest school (if not THE BIGGEST) of Anchovies on display, Mahi Mahi, Seven Gill Sharks, etc. Are way cooler in my opinion. But I think the Cherry on Top right now is their new Deep Sea Exhibit (The World's 1st Large Scale Deep Sea Exhibit). With all the Animals they're talking about potentially housing, AND THE ANIMALS THAT THEY'VE ALREADY CONFIRMED TO HAVE IN HOUSE such as:
-Bloody Belly Comb Jelly
-Mooderia Rotunda (Jellyfish)
-A Species of Siphonophore they actually cultured
-Salmon Snail Fish
And a couple unnamed species of Starfish, Sponges, and Sea Pens.
Along with the animals they have showed off for short periods of time in the past including:
-Juvenile Great White Sharks
-Vampire Squid
-Dumbo Octopus
-Glass Squid
-and 1 or 2 other Deep Sea Cephalopods.
In my opinion, the Technology and Scientific Advances made to now keep these Animals Long Term in Aquariums is far more impressive than what it takes to keep Whale Sharks and Manta Ray's (no disrespect) since they need Freezing Temps, Low Oxygen, and have to be collected by ROV.
While Keeping Whale Sharks and Manta Ray's is no joke, I just think that housing Deep Sea Animals that have never been on display and have taken Years of Advancement to crack the code into keeping them long term is a lot cooler.
