@Jonathan Harry That's interesting as maybe the zoo used to have Chimpanzees in the past. During my visit, I saw 14 primate species at Surabaya Zoo, including 5 types of macaque, but there was a grand total of zero chimps anywhere.
@Jonathan Harry There are photos of all the exhibits in the gallery, although I do have a typed out list of the 14 species: Bornean Orangutan, Siamang, Silvery Gibbon, Agile Gibbon, Proboscis Monkey, Japanese Macaque, Moor Macaque, Southern Pig-tailed Macaque, Crab-eating Macaque, Sulawesi Crested Macaque, Hamadryas Baboon, East Javan Langur, Tufted Capuchin and Ring-tailed Lemur.
