Some signs from my photos in the Gallery.
This is the sign listing the African and Asian elephants in the herd at Pairi Daiza. It is not particularly useful for identifying all the individuals, because the animals are split between at least 3 paddocks (one of which is enormous) and some of the younger ones are taken down to the lake to bathe.

The chimp recognition signs inside the house at Wingham.
The label for the giant tortoises at Blackpool, which mentions the question of whether the big male 'Darwin' might be a Seychelles giant tortoise, whereas the smaller female is definitely from Albdabra.
