Ryukin or Oranda whats the difference?

[osprey]

Can anyone tell me the difference between a ryukin and a oranda as i am having trouble seeing any variations other than colour.
Unless my local shop has supplied me fish of one type only.

I have no personal experience with either, but I found pictures of both. Looks like the biggest difference in appearance is the head. See what you think.

edit: It appears that the oranda doesn't get it's head growth until it's mature. Are yours young?
