Where
seen?
This beautiful nudibranch is sometimes seen at Beting Bronok, and
often encountered by divers on our reefs.
Features: 2-3.5cm long. Long narrow,
soft body with many long finger-like structures (called cerata) arranged
in about 8 fan-like clusters along both sides of the body. It is distinguished
by the purple body and yellow tips on the cerata with a band just
below the tip. The rhinophores are slender and tipped reddish purple.
It also has a pair of oral tentacles (like a moustache) which are
also tipped reddish purple.
