Where
seen? This blackish nudibranch is sometimes seen on some
of our seagrass meadows.
Features: 5-6cm
long. Broad fleshy body smooth, generally blackish with whitish speckles.
According to Bill Rudman, the white spots are of two different kinds.
Some spots are simply pigment spots on the skin while others are small
white glands producing a milky acidic secretion.
Sometimes mistaken for Dendrodoris
fumata which looks similar in shape and are red when young
and black as adults. Usually Dendrodoris nigra has 10 -15 smaller
gills forming a tight cup-shaped circle, placed further to the back
and lacks dark blotches on a lighter background. Dendrodoris fumata
has 5-6 large bushy feathery branching gills that when expanded, may
cover the width of the animal. But the species can be definitively
told apart only by looking at small internal features.
