NOTE: Strictly speaking, you're not allowed to take photos at all at this zoo. However, the first thing we were greeted with was a member of staff taking flash photos with a large camera of a disagreement between two Mugger Crocs, so they clearly have no concerns about the animals' response to being photo'd. Given that, as a open-to-the-public collection, there is no question of prvacy or secrecy, the rule seems to smack of nothing more than officiousness. The contents of the building are public, and the rule does not seem to exist for the animals' benefit. So I discreetly disregarded it. ;)
