Ghost, our male albino checkered garter snake, was an inadvertent case study on whether caloric restriction correlates with longevity. He was never a particularly enthusiastic feeder, preferring smaller, less frequent meals: if you tried to feed him weekly or even biweekly, or a meal commensurate with his size, he’d be prone to refuse. Even by male garter snake standards he was underweight, and in recent years he looked positively gaunt. Fragile, even. Yet somehow he managed to live longer than any other garter snake in our care. When he died yesterday, he’d been with for more than 16 years: I got him in April 2005. And he wasn’t a baby then: I think he was born in 2003. Which would have made him 18½ or so when he finally went—older than Extrovert, our female wandering garter snake, who died in 2016 at the age of 17.
