Where
seen? This large flat nudibranch is often seen on many
of our shores, usually near coral rubble or reefs. Sometimes, several
may be seen during one visit.
Features: 10-12cm long. The hard
body is broad and rather thin and flat, and covered with small brown-tipped
bumps. Distinguished by the prominent hump along the centre of the
otherwise flat animal. Patterns and colours are quite variable, generally
brownish to black with paler markings. The flower-like gills are dark
brown with white lines.
It is named after the Bohol Islands in the Philippines.
Avoid handling the animal as it easily breaks off (autotomises) portions
of its body (mantle skirt). Under the mantle skirt is the foot with
another pair of tentacles.
What does it eat? It eats sponges.
