Hallaxa fuscescens - feeding observations

August 21, 2006
From: Bill Rudman

Hallaxa fuscescens is another species of Hallaxa which I have found feeding on a species of the 'slime sponge' Halisarca. The sponges are so named because they are often form a thin smooth slimy film over the rock on which they are attached. Often they are not noticed. In the upper photo, the sponge colony has been reduced to scattered fragments by the feeding activity of the 5 animals I found on it.

Locality: Arrawarra Head, Coffs Harbour, nthn New South Wales, Australia. Intertidal, 16 March 1982, live length of pictured animal, 18 mm. on Halisarca sp. AM. C115783
