Manta ray logos

I need to come up with an image to represent a manta ray for the net brief and as part of the on going print brief.
The manta ray is quite a strange animal in the way it looks and it is relatively unknown to a lot of people so representing it might be quite difficult. I don't want to have a picture of a manta ray that people look at and don't understand.
I found these existing examples of different representations of manta rays.
