May 2020
Where
seen? This pretty nudibranch in a pin-striped suit is commonly encountered
on our Southern shores among living reefs and on coral rubble. Towards the late 2010's, they have also become commonly seen on our Northern shores. 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 sponges, including the Silvery blue sponge.
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. |
About 12 animals gathered together!
