The Singapore Zoo has three white tigers, Omar, Winnie, and Jippie.

Earlier this year, 9-year-old Omar was short-listed as a possible contender to replace Ah Meng as the zoo's icon.

The 48-year-old orang utan died suddenly during breakfast on Feb 8.

When the zoo introduced boat rides last month, one of the four boats was named after Omar.

Only one white tiger exists out of every 10,000 normal orange-coloured tigers.

A report published by the World Wildlife Fund highlighted the possible extinction of tigers within a decade if inadequate conservation measures are taken to protect the tigers.
