[Note Guidelines] Photographer's Note
Nudibranchs form one of the main divisions w/in
Mollusca. Nudibranch means 'naked gill'.
They are popular in reef habitats and
feed on algae and sponges and such.
They come in a variety of shapes and sizes.
The average length is between 3 to 300mm. This one is about 40 mm. The flesh is frequently toxic or distasteful due to various chemical secretions. The bright “poster colored” patterns serve to warn potential predators of their inedible qualities.
Both sexes are present in a single nudibranch, but self-fertilization does not occur.
Because of their color they are sometimes referred
to as jewels of the sea.

This photo was taken at Flinder's Reef offshore
from Brisbane Australia in about 15m of water.
Ikelite housing and DS50 strobe. Just looks
like this guy is in a different world.
