Rose nudibranch
Dendrodoris fumata
Family Dendrodorididae
updated Oct 2019
Where seen? This brightly coloured rotund nudibranch is sometimes seen on our Northern shores, near boulders with sponges and other encrusting animals.

Features:
5-8cm long. Broad fleshy body smooth, generally all red or rose with irregular dark mottling, sometimes greyish-pink. Underside paler. It is said that it turns black as it matures, but some apparently remain red.

Sometimes mistaken for Dendrodoris nigra which looks similar in shape and are also 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.

What does it eat? It eat sponges. It lacks a radula and jaws so it can't rasp or chew its food sponge. Instead, it secretes digestive juices onto the sponge and then sucks up the softened sponge with a long tube. Sort of like a sponge slurpee!
