Ears can come in a variaty of forms, here are some things to keep in mind:
- Extra long, big, multiple ears and bones or skulls require the respective anatomical traits
- Object or elemental ears require the respective compositional traits
- Living ears of any type require the "independently living body part" trait
- Hand like ears and prehensile ears are ok for limb ears and do not count as independently living unless that's the clear intention (having eyes and a mouth, fe)
