Where
seen? This colourful nudibranch is sometimes encountered
on some of our Southern shores, on coral rubble and reefs.
Features: 4-5 cm long. Body long,
hard with bumps (called tubercles) without feathery external gills
on the back. Distinguished by 3-6 ridges of bumps along the length
of the body. The bumps are blue-grey where they join the body and
tipped yellow. The short rhinophores are orange. It has a black stripe
along the length of its foot. It secretes noxious substances from
glands in the white coloured portion of its body. |
