Traits

Ears that turn into a fin. The fin looks like a second pair of ears.

Fleshy/scaley ears that remind of angler fish fins.

These ears are having feathers grow on them. The formation  on the bottom looks like a second pair of ears, but it is only feathers.

These ears can ONLY be obtained via Quest.
These cannot be bred. If both Shijis from the pair should have these ears, you can decide which two ears should be chosen in their stead.
The ears resemble little wings, they can move, but not function like real wings. The ear opening is right at their base.

(Note: Normal Shijis can also obtain these ears, it is unchecked simply for the gambling algorithm!)

Ears that have feathers growing out of them. The feathers usually start at the eyebrows but do not have to.

Nubian ears consisting of feathers.

Sun ears have very short fur and have parallel stripes coming from them.
