The oldest land animal is celebrating a huge milestone birthday this year.

Experts believe the little guy, who resides on the island of Saint Helena in the South Atlantic, where he moved to back in 1882, was born in 1832.
To put his impressive life into context, Jonathan is older than the electric lightbulb and the motorised car, so he's seen a fair few changes over the years.
According to Guinness World Records, he is the oldest ever chelonian, which encompasses all turtles, terrapins and tortoises.

His best mate, the second oldest tortoise on the island, is called David and is just 80 years old.
The previous oldest chelonian was Tu’i Malila, a tortoise who is thought to have lived to be around 188, having died in 1965.
He was presented to the royal family of Tonga by British explorer Captain James Cook in about 1777.
Joe Hollins is a veterinarian who has cared for Jonathan for the past 13 years.

Speaking to the Washington Post about their relationship, he said: "I take great delight in looking after him.
"It’s a huge responsibility, but an honor and a privilege for a vet to see to the needs of the oldest known living land animal in the world.
"While wars, famines, plagues, kings and queens and even nations have come and gone, he has pottered on, totally oblivious to the passage of time.

“Jonathan is symbolic of persistence, endurance and survival and has achieved iconic status on the island."
In recent years, Jonathan, who is now blind, has suffered with a bit of ill health.
Joe recalled: "He was grabbing at dirt and dry leaves and tugging on rank grass. After feeding him for some time, we witnessed a miracle: his beak regrew its sharp edge."
The vet eventually discovered that Jonathan had a vitamin deficiency, which he was able to fix by introducing fresh produce into his diet.
Fellow caretaker Tina Lucy added: "We started feeding Jonathan on a weekly basis a few years ago to supplement his grass diet and boost his nutrition.

"This was because the island vet realized that his beak was soft and crumbly and that he was too cold and had lost weight. All that has reversed now and he is as fit as a fiddle!
"He knows my voice and he knows the vet’s voice and reacts by walking toward us. It’s all about the food!"
Well, we're glad he's got such a top team around him.
Happy birthday, Jonathan!
