Where
seen?
This
tiny nudibranch is sometimes seen on coral rubble and seaweeds near
reefs on our Southern shores. Relatively regular encounters suggest
they may be quite common but often overlooked because they are so
tiny and usually buried.
What does it eat? According to
Bill Rudman
some species eat soft
corals and sea
fans.
