Where
seen? This small black nudibranch with pink bumps is among the more commonly encountered
on our Southern shores, near coral rubble and reefs.
Features: 4-5 cm long. Body long,
hard with bumps (called tubercles) that are evenly distributed throughout
its body (not clustered in groups or in ridges along the body). The
bumps are tall and rounded, are pink to red near the tips, but black
where they join the body. The short rhinophores are black. When disturbed,
it secretes a milky substance. The broad foot on the underside is
bluish and does not have a line along the centre. |
