yeah, the inside of a reaper looks different depending on what species it was made of. like a turian reaper, an asari, or volus, or prothean. actually, a 2km tall garrus reaper would make my life meaningful.Zhukov said:It explains this somewhere in the codex thingy.
The thorn bug/cuttlefish form is like armour or a shell. Inside they presumably all look different.
Of course, the real reason for this is that they just couldn't be arsed coming up with a unique design for each reaper.
