Favorinus mirabilis is pretty variable in its colour details, most specimens have a distinct orange-reddish median line on the head,
and white speckling on the cerata which have a purple spot near the tip. It has perfoliate rhinophores, very variable in its colour,
ranging from translucent, to brownish, to black, often with a white apex.
The oral tentacles are often yellow-orange with white specks or patches.
It feeds on the eggs of other sea-slugs like all members of the genus Favorinus.
The colour of the cerata depends on the colour of the eggs it has been feeding on.
