Purple branching sponge
Callyspongia sp.*
Family Callyspongiidae
updated Oct 2016

Where seen? Like a little purple bush, this sponge is commonly seen on hard surfaces near the mid-water mark on our Northern shores.

Features:
A bunch of 'stems' slender (1-1.5cm thick) and long (10-15cm), usually growing upright but sometimes sprawling horizontally hugging the surface. The stems are not extensively branched and cylindrical with rounded tips (not tapering). With small shallow holes regularly spaced along the length of the 'stem' (not just at the tips, and the 'stem' is not a hollow tube). The surface texture is rough. Colours usually purple to lilac.

These sponges are draped with sponge synaptid sea cucumbers at some times of the year.
