Ghost Shark

Ghost shark (aka abyssal shark, [pointy-nosed blue chimarae](https://en.wikipedia.org/wiki/Pointy-nosed_blue_chimaera)) sculpt. One of those deep-sea animals that reminds us, yet again, that the the abyss is a very strange and frankly scary place.

I've updated the file so that the pupil is now a separate object: if you have a multifilament setup, you should be able to fill the pupil with a translucent filament during your print to mimic the real shark's blown-out pupil.
