Hollow object with media in a hollow object with media means the inner
object gets both medias inside.

See hollow2.pov in ./scenes/interior/media/

You can replace the third sphere with this code to clearly see the effect :

=== Begin sdl code ===
//
// Hollow, translucent sphere enclosed by media.
//

sphere {<29, 20, 0>, 25
 pigment { rgbt <1, 1, 1, 0.9> }
 finish {
  ambient 0.0
  diffuse 0.0
  phong 1.0
  phong_size 200
 }
 interior { ior 1.1 media{absorption 1 density{dents} }
 }
 hollow yes
}
=== End sdl code ===


The solution is to difference your sea object with an invisible clone of
your jellyfishes - beware of coincident surfaces...


I hope this helps.

Povingly,
