The Australian marsupial - who goes by the name Wain - was given the title of oldest ever wombat in captivity with a bit of fanfare at the Satsukiyama Zoo in Japan by the Guinness World Records.

Zookeepers celebrated the wee fellow’s birthday in January, making him older than the previous record holder - who died aged 32 in 2017 in Australia - and higher than the average age of a captive wombat, which stands at between 20 and 25.

Taiki Endo, the zoo’s deputy director said: “I hope he will continue to show his activeness and friendliness to visitors.”

According to the Ikado-based zoo, Wain - who is one of six wombats at the sanctuary - is considered to be in good health,aside from being afflicted with cataracts. The little guy was donated to the zoo in 1990 when he was a one-year-old joey.
