Melbourne Zoo’s oldest residents have been helping their keepers, showing no one’s ever too old to learn.
Asian elephant Mek Kapah and Aldabra giant tortoises Wilbur, Little John and Jean have all learned to help out with their own health checks.
The tortoises, aged between 60 and 110 years old and weighing up to 200kg each, have been trained to lift up their feet and allow keepers to check for cracks and dryness.
“As part of their ongoing healthcare plan, we want to make sure they’re always going to be healthy and fit,” said reptile keeper Raelene Hobbs.
“One way of us doing that is making sure we provide them with choice and control to participate in their healthcare.
“They are starting to age and, as part of that, we would expect to start seeing things like cracks and dryness of the feet, or scutes* coming off. So we like to check them quite regularly.”

The health check uses a target training program, developed by keepers over the past 15 years, that associates some of the tortoises’ favourite foods with a red target. Red is one of the few colours giant tortoises are able to see. This encourages the tortoises to present their feet for inspection.
“It’s a wonderful program,” Ms Hobbs said. “They pick it up really easily. The moment I show them that red target, they switch straight back into it.”

Aldabra giant tortoises are one of a few surviving species of giant tortoise left in the wild and have been estimated to live up to 200 years. Wilbur is the zoo’s oldest resident and is thought to be at least 110 years old. Little John is thought to be at least 90.
These tortoises are listed as vulnerable in the wild by the International Union for Conservation of Nature’s Red List, due to poaching* and habitat destruction.

LOOKING AFTER MEK KAPAH
It’s well known that elephants have long memories and that’s certainly the case for Melbourne Zoo’s oldest elephant and herd matriarch* Mek Kapah.
The 48-year-old Asian elephant has learnt how to participate in her own health care, responding to keeper directions and standing still while she has her eyes examined.
Mek Kapah’s keepers suspected the ageing elephant’s eyesight was becoming blurry, so organised the examination by veterinary ophthalmologist* Dr Anu O’Reilly.
“Our keepers have noticed that, for a little while, she has been showing signs that she might be having some vision problems,” said Melbourne Zoo vet Dr Kate Bodley, who supervised the examination.

After a thorough examination, Dr O’Reilly discovered Mek Kapah is experiencing the early symptoms of lens changes, which affects the eye’s ability to shift focus, typically a result of ageing in both animals and humans.
“We did find that she had some very mild, very early changes to the lenses of both eyes that would explain why she has been showing us some very mild signs of vision change,” said Dr Bodley.
“She’s an older elephant and lens changes frequently happen in older animals, which just means her vision’s not as clear, and things are possibly looking a little bit fuzzy.
“If she’s in an area where the light is low, or if she is doing something and not concentrating, she might find that her judgment of depth might be not as good as it was.”
The diagnosis* was considered “a good result” by Dr O’Reilly and Dr Bodley, who said that Mek Kapah doesn’t require specific treatment at the moment.
If Mek Kapah was a human, an optometrist might prescribe glasses to help her see clearly. However, in Mek Kapah’s case, keepers will modify her environment, starting with white paint to mark certain areas in her training spaces, removing the risk of her bumping into anything. Her eyes will be checked every three months.
At 48, Mek Kapah is considered elderly for an Asian elephant.
Asian elephants were once widespread throughout Asia, but are now classified as endangered by the International Union for Conservation of Nature’s Red List, with only an estimated 40,000 remaining in the wild. Zoos Victoria’s ‘Don’t Palm Us Off’ campaign aims to raise awareness about unsustainable palm oil production in the habitat of the Asian elephant, calling for the clear labelling of palm oil on products in Australia.
