For large animals I am impressed with crocodilians as for longevity. Hundreds of millions of years. Survived ice ages even. We have been speciated for less than three or five hundred thousand years and I would venture to say our future is somewhat doubtful already. Crocodilians and sharks are efficient at what they do. Thermodynamics and entropy reward efficiency. We are the opposite of that.
True, but we have the game-breaking meta build of intelligence, socialization, and tool use. A complete game-changer. Incredible inefficiency as the trade-off for virtually limitless potential. The downside of being able to do whatever you want is that you can do whatever you want - including destroying your own resources.
