An animal so impossibly beautiful, so psychedelic, it leaves us slack-jawed in the face of nature’s awesomeness. From Wikipedia:
The normal size of this species is up to about 3 cm, depending on the animal’s age. It is silvery grey on its dorsal side and dark and pale blue ventrally. It has dark blue stripes on its face. It has a tapering body which is flattened and has six appendages which branch out into rayed cerata. Its radula bears serrated teeth on their blades.
