As children and other spectators sang to mark her 55th birthday, Thailand’s oldest hippopotamus Mae Mali chomped on an assortment of fruit and vegetables arranged in the shape of a cake.
Mae Mali, which means Mother Jasmine in Thai, moved to a compound at Khao Kheow Open Zoo in eastern Thailand two years ago from a zoo in Bangkok. She has already outlived a hippo’s typical life expectancy of around 40 to 50 years old.
Mae Mali gave birth to numerous calves, and her descendants, now 21 hippos, reside in zoos across the Southeast Asian country.
In the wild, the hippopotamus lives in rivers and lakes in sub-Saharan Africa and habitat loss means it’s now considered vulnerable.
In the neighbouring Philippines, Bertha, considered to be the oldest hippopotamus in captivity at the time, died in 2017, aged 65.
Another hippopotamus, Lucifer or Lu, is reported to have celebrated his 60th birthday at a wildlife park in the US state of Florida in January this year.
With adults weighing from 1,500 kilograms (3,304 lbs) up to 3,200 kilograms, the hippo is the second-heaviest land animal after the elephant, spending the heat of the day in the water and coming ashore at night to feed on grasses and fruit.
