Merlin Entertainments has announced the acquisition of Istanbul's Turkuazoo Aquarium from Dutch-based company Global Aquariums BV for an undisclosed sum. Attractions Management - Merlin secures Turkuazoo Aquarium acquisition
According to the article linked in the first post, there are 45 aquariums and marine sanctuaries (although there are only 40 listed on wikipedia). Presumably this doesn't include their other terrestrial wildlife attractions, and obviously not the rest of their 'cultural' attractions.
Because there wasn't enough confusion between this establishment and Akvaryum Istanbul, Turkuazoo has completed being re-branded into Istanbul Sea Life Akvaryum
I get 49 from a count-up off the SEA LIFE site (including attractions featuring SEA LIFEs, such as LEGOLANDs): https://www.visitsealife.com/ EDIT: oops, just realised zooboy28's post was from two years ago!
