I would name it 'The Aquarium and Zoo of Almighty God's Creation' or 'Darwin's Critter Jubilee' depending on which way I am swayed in the Tulsa Zoo exhibit debate!
I've got several names such as
"Northback Zoo"
"Demagate National Park"
"Yaythere Park" p)
"NI Zoological Gardens"
and one I'm particulary fond of...Emblem (Zoological Gardens)
