Tribal Anatomy

Feral and Tribal Hewan have no difference whatsoever in physical appearance, other than Tribal Hewan usually being more clean/neat looking and wearing loincloths, at least for those out of water.

Aquatic
Aquatic Hewan have no legs or lungs, but they do have arms and webbed fingers. They posses gills and typical fish/shark/other anatomy like fins

Avian
Avian Hewan resemble harpys. They do not have wings on their back, instead having wings like a bird, not having separate arms and wings like a sophisticated. They have raptor-like posture (Hunched over with their arms out in front of them) and their feet are like that of a chicken's.

Mammalian
All mammalian Hewan are like wereanimals. They're hunched over, some of them on all fours, and have very human-like faces. A wolf Hewan would be just like a werewolf, aggression and human features included.
