"How and Why We Age" by Leonard Hayflick, page 21 of the first edition.
He claims that animals such as some fish, amphibians, and reptiles (like
the Galapagos tortoise) appear not to age -- they don't age at all or
age so slowly that we are not capable of determining it.

Erik wrote on the same subject (and my reply also applies to what Tony

It's a good idea, but I would focus on their evolutionary path rather on
their habitats. For example, do you know that mammals can't produce
ascorbic acid (a powerful anti-oxidant)? Little mistakes like that might
be behind aging! And did you know that the Galapagos Tortoise's cells
have more anti-oxidants than our cells (also taken from Hayflick's
book)? There are many other interesting phenomenons, I'm actually trying
to make a list of them (will be probably ready in a couple of months).

The only site I know in the Internet that mentions non-aging species
with some detail is my own. The URL is:

See ya,
