I'm happy to be corrected, but I think they are:
Red-fronted brown lemur (male)
Mongoose lemur (female)
Red-bellied lemur
Ditto
Red ruffed lemur
Thanks for the photos. Can you do a detailed review of the zoo please? I saw a bit of it on Zoo Days about the transfer of Jambo the elephant from Colchester to Valencia and the park looks really good. What do you think of its overall size? It must be using a lot of water as it looks so green, but I suppose that's nothing to what all the local golf courses must be consuming. I'm going later this year when I'll visit Oceanografic too, I can't wait.
