Where
seen?
This black nudibranch with prickly bumps is sometimes seen on some
of our shores, on coral rubble. It was previously known as Trippa
intecta.
Features: Variable in size, sometimes
1cm long, others up to 6cm long. Very dark maroon, almost black. There
are tiny prickly bumps all over its body. The feathery gills appears
similar to the rest of the body. The species should have a line of
pale or beige bumps along the upper body length, but none of those
seen had this. The foot has small white spots on the upperside and
is smooth and lighter on the underside. |
