Sorry for the wait!!!
I'm a fish
I'm notoriously territorial and will attack almost anything, including divers
I'm found off the coasts of north and central america
Males of my species possess a blue and gold ocelli on their dorsal fins
Nope
My bald head is blue and so are my feet
I have two smallish feather tufts near my tail that I can fan out
I am found in certain regions of south america
:) That was a good one
I am a mammal
I am a marsupial native to Australia and New Guinea
I am an omnivore with a diverse diet
I am hunted for meat and pelt but not threatened
What am I?
