Things just don't seem to die in the deep ocean (well, except for humans). While rockfish nearer the surface live about 12 years, those living closer to 2500 feet down can live for 200 years. There's a deep water coral that can apparently live as long as 4,000 years. But there's one species that seems to live an especially long time, and could rank up there with the oldest: Escarpia laminata, some dumbass tubeworm.
