our shores, among seagrasses, seaweeds and near reefs. It is more active at night.

narrow and somewhat cylindrical, pale or white with net-like pattern
of red lines. Two rows of finger-like appendages along the body, not
true cerata. 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. |
