Articulated sea slug / leaf sheep.

I printed in a glow in the dark filament for the green and purple tips. However i was disappointed in the green. if i printed again i would use a bright green to more closely match the sea sheep's actual colour

This is based on a real sea creature, known as the leaf sheep (Costasiella kuroshimae) contrary to what its name suggests, the leaf sheep is neither leaf nor sheep – it's actually a sea slug, and there is a photo included at the end of a real leaf sheep for those who are interested
