Text page icon Description The yellow staghorn sponge resembles the horns of a stag. It has finger-like branches in a rough fan-shape, usually in one plane. It is usually about 15 cm high and yellow or orange in colour. The branches are almost oval, rather irregular in diameter along their length, and around 1.5 cm long. There is a short stem at the base which is thicker than the branches. The surface of the sponge has a velvety texture and is moderately firm but elastic.
