You would think at 100, an animal would be either dead or almost there. At 183, Jonathan, a giant tortoise is living like a king. He is living on a small island of St. Helena. Just recently, he was eating twigs, leaves and grass which is an unhealthy diet for him. Now, he is being served a much more nutritious and delicious diet plan including apples, carrots, cucumbers, bananas and guava. Before the diet change, Jonathan's beak was soft and blunt, changing his diet made his beak sharper and easier to graze with.
"His once blunt and crumbly beak has become sharp and lethal, so he was probably suffering from micro deficiencies of vitamins, minerals and trace elements," Hollins said in a statement.
Over time Jonathan lost most of his eye sight, his sense of smell and his ability to mate.
In Hollins report it read "Once weekly I hand-feed him to boost his calorie intake," Hollins wrote in the report. "After his meal, I wipe his chin, scratch his throat and wish him well."
Seychelles giant tortoises have a life expectancy of 150 years, but Jonathan has obviously strongly outlived this. Other long-lived animals include the hydra, a marine mammal that is believed to be immortal and an approximately 4,200-year-old deep-sea coral living off the Hawaiian coast
