Eh, might as well compare apples and oranges and expect it to describe a banana.
Most animals that live well over 100 years have a very low metabolism. For example turtles and tortoises. Other living organisms that have biological immortality are generally simple creatures. As in all the components of the creature can be replaced and the creature doesn't change in function. Fish, for example can live hundreds of years, but their biology is considerably different than a mammals. That said, whales and alligators can have extremely long lives. It may be that water acts as sunblock and reduces the amount of UV damage allowing life to continue much longer than most land animals.
Right, but it puts a lie to many of the theories that involve mortality being an inevitable result of biological chemistry -- e.g. that cells can only divide so many times before they MUST die.
The reality is that for just about every aging related failure mode, there is an example of some animal somewhere that is able to fix or otherwise defend against that very form of damage, a proof by example that such damage is not inevitable or irreversible.
