I could swear I posted here, commenting on how dumb picking over "a best animal" would be in my opinion.
Oh, of course I'm going to say humans are the best animals. I defintely agree with 1337Players. It's only a matter of decades before we become superhuman cyborgs. Then any poor lad will be able to kill a wolf with his bare han.. I mean his amazing strength.
Best mammal would have to be the honey badger; he isn't so big but is ferocious and can fight off animals several times bigger than him; he has a thick skin that protects him against all sort of stings, claws and bites, he is immune to some very potent venoms and thus can eat certain snakes.
Land- Honey Badgers or bears.... they're both ferocious Sea- Squids... squids are just amazing.. they eat other squids... they have a difficult life Air- the Bald Eagle...it looks powerful... and it is powerful
