Nautomorph

I call it the Nautomorph. Always wondered what a translucent version of a Xenomorph would look like, plus added some bioluminescence to complete the deep water look.

Tail detail. All the spikes are completely translucent. The illuminating organs sit within smal skin pockets in the tail.

Lower body detail. The ripped translucent skin allows to see the blurred muscle structure underneath.

Head detail. Elongated pointy flat chin for better aquadynamic motion.
