It's quite a long and heavy list so I've broken it down into sections, as well as a brief summary of each area:
On entering the centre and walking past the main desk, there’s a dark room with a big screen showing footage of endangered Arabian animals. After walking through the room, there’s a large reptile room, with a big enclosure for desert monitors in the centre and smaller tanks/vivaria for snakes, lizards, toads, fish and arthropods all around.

The second main area is a large indoor aviary for native birds and Arabian hares. It is very well-themed with large boulders, waterfalls and a flamingo pool. One darkened side room houses skittering frogs, and another (a cave) houses Egyptian fruit bats and Omani blind cave fish. Glass windows near the far end of the aviary look into indoor enclosures for Schmidtz’s caracal, Indian grey mongoose and sand cats.

EDIT: Just thought I'd include a link to the official web page and a brief statement on each of the four photos they've published to help visualise:
http://www.breedingcentresharjah.com/Wildlife Centre.html
The first photo shows a viewing area for one of the carnivore enclosures. The second shows a very small section of the large walkthrough aviary. The third photo shows one of the side-bays in the reptile room for snake or lizard enclosures. The fourth is a view from the rocky cliffs for hyrax & ibex in the restaurant enclosure; the restaurant is the round building with a blue roof.
