I just figured out that groundhogs will NOT live forever with the best medical care. Then I researched cicadas and discovered the same thing (that they don't only die by external forces). Are there any other animals that /an/ thinks/thought were immortal?

No, I've never been that naive.

Nature's Juggernauts. Or Superman, if you're into DC's overpowered bullshit.
Acid, heat, cold, pressure, vacuum of space - none of this means anything to them.

Only problem? SQUISHABLE.

I had a microbiologist friend who believed water bears were elaborate hoaxes.

There's also some species of sea anemone or something similar, the name of which does not spring to mind.

I think most anemones and coral (all animals) only die from outside forces as well. They live until something kills them. Wow thats redundant

The hydrozoan Turritopsis nutricula has evolved a remarkable variation on this theme, and in so doing appears to have achieved immortality. The solitary medusa of this species can revert to its polyp stage after becoming sexually mature (Bavestrello et al., 1992; Piraino et al., 1996). In the laboratory, 100% of these medusae regularly undergo this change. Thus, it is possible that organismic death does not occur in this species!
