Where
seen?
This pretty nudibranch in a pin-striped suit is commonly encountered
on our Southern shores among living reefs and on coral rubble. Sometimes,
it can be seen in large numbers.
Features: 2-3cm long. Long body
with broad tail, black with fine white lines. The body and the foot
are edged in a broad yellow or orange border with a black line along
the inner edge of the orange border. The tips of the flower-like gills
and the rhinophores are maroon to pink. The similar Chromodoris
striatella has a white body with fine black lines and a white
line along the inner edge of the orange border.
Sometimes
mistaken for armina nudibranchs.
The Lined chromodoris nudibranch has a feathery gill on its back while
armina nudibranchs don't. |

What
does it eat? It eats a blue encrusting sponge (previously
called Dysidea herbacea now known as Lamellodysidea
herbacea).
Members of the Family Chromodorididae absorb the toxic chemicals
in their sponge food and incorporate these chemicals into
the mantle glands on their backs where they repel predators.
