  To answer your question, FL, my information is that the eye in the first one is not supposed to be open, but it is a black dot, and doesn't look anything like what it should.  I think perhaps that one should be left out.  As far as the others, they leave out a great deal of detail.  I don't know they are not accurate, just they don't really present the whole picture (much like the sonograms).  But I believe you about the gills and tail, lol. 

 Antelan, which details have been selected to not show?  This is something I don't know.  ——''''''     Ψ —— "
