A giant barrel sponge growing on a Caribbean reef off the island of Curaçao was estimated to be roughly 2,300 years old when it was photographed by researchers — meaning it began growing at the bottom of the ocean during the lifetime of Hannibal and survived as a single continuous living organism, filtering seawater on that exact spot, from before the founding of the Roman Empire until it died of disease in 2012

Hannibal was 28 years old, still a few years away from leading 37 war elephants over the Alps to invade Italy, when somewhere beneath the warm shallow water off what is now Curaçao a microscopic blob of cells the size of a grain of sand settled onto a piece of coral and started doing the only thing it would ever do.
