Tortoise Celebrates 187th Birthday As Oldest Living Animal On The Planet

It's interesting that there's a photo of Jonathan taken way back in 1886, and it can be compared to his present photo, just like a modern #187yearschallenge. It's noteworthy that the tortoise was already around 54 years old when that photo was taken. Although Jonathan is still lively and full of energy, signs of aging have been observed by doctors, and his sense of sight and smell are slowly getting weaker. Dr. Hollins feeds Jonathan with special food with higher calories on a weekly basis, since he doesn't eat enough grass anymore.
