Rachel Sussman has travelled the world to take photographs of the oldest living things in the world. This is actinobacteria from Siberia; it's 400,000 years old.
There's a map and a progress blog and an unassociated Wikipedia entry that tells of the ocean-going species Turritopsis nutricula:
The Hydrozoan species Turritopsis nutricula is capable of cycling from a mature adult stage to an immature polyp stage and back again. This means that there may be no natural limit to its life span.
Who wants to bet that Ray Kurzweil drinks a Turritopsis nutricula smoothie every morning? (via @bobulate)
