Yellow pot sponge
Rhabdastrella globostellata*
Family Ancorinidae
updated Dec 11

Where seen? This rather large, pot-shaped sponge is commonly seen on our Southern shores, among coral rubble.

Features: About 12-15cm wide, a squat sphere with one or several shallow depressions at the top, so that the entire sponge resembles a shallow pot. The depression is smooth and often has many closely-spaced holes that resembles holes in cheese. There are bumps on the outside of the 'pot', sometimes forming ridges. Colours range from dull yellow to brownish or beige.
