Sumatran Rhion Begum

But there is a Damian Aspinall
I'd love to see these some time, probably will never happen though.

The two females at Port Lympne did not live there very long. I don't know if the male Torgamba developed eye problems during his much longer residence there, but I believe it is related to bright/intense sunlight which the Uk doesn't get a lot of.

The only problem the Port Lympne animals seemingly had was that both females were apparently elderly when they arrived, and probably past their breeding span.

But I don't think PL will ever keep this species again,(even if they became available) having failed to breed them.

London Zoo's long-lived Sumatran rhinoceros, “Begum”, was the type specimen of the sub-species Dicerorhinus sumatrensis lasiotis

Port Lympne had a really good outdoor paddock for the sumatran rhinos, with natural ground, water, mud, trees, grass, everything they need, but nevertheless, they had bad luck. The first female died soon after the arrival, and the second,"Meranti" was sterile, she was unable to breed.

The first female to arrive at port Lympne had an old leg injury from a poachers snare and not a young animal

The PL animals were unlikely to have eye problems if this is connected to UV light as the paddocks were in a wood (although the lower one had a more open grassed area towards the lower end. As pertinax says, a good barometer might be the incidences of cataracts in malayan tapirs in europe, which I believe are very low. I know the original female at London (in recent decades) had cataracts, but at the time of her arrival I don't think there were many at all in the UK and she may well have been imported.
