These appendages are usually orange tipped, and protect feathery white gills, and conical orange rhinophores. The oral tentacles near its mouth have star-like or hand-like tips. 'Stellifer' means 'star-like'. It can swim by flexing its long body from side to side.

What does it eat? It eats small hydroids growing on or under rocks and hard surfaces.
