I've just found time to look through all of those. One hundred photos! I like how they have life-size models of the giant Asian fish (the stingray etc) to show how big they will grow. And the giant otters look like they have a huge tank for swimming in, which is good. (Not too sure what they mean when they say that the River Safari is the only wildlife park in the world to display them however!)Lots of photos on this news site, practically all the major exhibits are shown:
