"Glass sponges are considered the oldest animals on Earth—and it’s by a long shot. Scientists estimate that they can live for more than 10,000 years, possibly 15,000 years maximum. One glass sponge observed by researchers in the Ross Sea, a bay of Antarctica, is thought to be the oldest living animal on the planet. Scientists have also discovered a skeleton of a glass sponge in the East China Sea that they believe lived for 11,000 years. These individual animals are so old that they could have been alive during the last ice age. "
