I am changing my sea animal to colossal squid, and yes there is a difference.
Humans
Humans are silly. The only reason they're still alive is because of "intelligence" and "invention" and "creativity". Any unarmed human could be easily killed by most other animals. (Note that the animals would also be unarmed (Since you really can't call claws weapons, since they're natural and stuff) )
best animal? planaria. they can be split and regenerate. like you can go and say. hey i need a few people to help me out, what? no one? okay fine i'm going to split in to 3 pieces, and then get all the help i need
If we're going on that line I would say Turritopsis nutricula, a jellyfish that has the ability to revert to polyp stage when the conditions are bad, thus being potentially biologically immortal.
Land = Lion Sea = Megalodon (Who said we had to stick with current animals?) Air = Any kind of Hawk Carnivore = Humans (We will eat anything) Mammal = Humans (We have dominated the earth)
Humans are not carnivores... i did the land/sea/air earlier... so the best carnivore/mammals are as follows: Carnivore: i'm going to say the Sydney funnel web spider... it's big... poisonous.. and it has been alive for a really long time mammal: chimpanzee... or Humans.... humans are more intelligent.. but chimps are pretty intelligent too... and chimps are much stronger than humans
Humans can be anything they want, most are omnivores but some become vegetarian/vegan and are thus herbivores. I have also known people that only eat meat. Humans can be anything they want regarding food intake depending on their personal values/ideas/morals/etc.
if someone ate only meat.. they probably would not live long... humans arent well designed to eat and digest meat. our anatomy is geared towards a fleshless diet
