Nah, snakes and jellyfish serve a valid purpose in the ecosystem.

But yeah, mosquitoes and cockroaches should be made extinct, even if they are tough critters.

Talking of tough though..

Say hello to the only creature that's evolved to cheat death itself: the Immortal Jellyfish. https://en.wikipedia.org/wiki/immortal_jellyfish

As I understand it, scientists believe that lobsters are also functionally immortal, just not invulnerable. I think the problem is that after a while, it takes so many calories to continue molting, they simply can't hold enough in their bodies or something? Anyways, they don't have an old age problem like you'd expect.
