i found this husbandry manual for tapirs on the net.. www.tapirspecialistgroup.org/Downloads/ standards/tapir-TAG-husband-stan-en.doc - although it does not go into much detail about the eye problems that are particuarly prevalent in the asian species it does attribute it closely to not having adequate amounts of shade in the exhibit. i mentioned earlier that it was my belief that malayan tapirs are noctournal. however this document states that they may be crepsular, diurnal or noctournal though it is talking of tapirs in general and is not species specific. although the melbourne and sydney tapir exhibits provide adequate shade, as anyone who sits in the shade on a bright day knows, this doesn't neccersarily stop glare from surrounding sunny areas. i would be interested to know if adelaide's malayan tapirs have the same eye problems and whether any zoo has ever attempted keeping the animals in very dim holding yards or indoors during the day and only allowing them access outside at night. the manual also mentions that although tapirs seem somewhat inactive - large terrestrial areas for excercise and breeding behaviour is important. though i think it is not desireable, i have seen tapir exhibited without pools at all and i would guess land area is far more important than swimming space. the taronga exhibit did not look particuarly shady or large in land area, but addmittedly i have not seen it.
