The yellow boring sponge inhabits living bivalve molluscs, boring into the shell valves. The only parts of the sponge which are visible from the outside are small yellow patches up to 3 mm (0.1 in) in diameter, sometimes containing small oscula (openings). The sponge spicules are silicaceous (glassy) and are scattered throughout the sponge tissues.
It is a hermaphrodite; the gametes are released into the sea where fertilisation occurs, the larvae are planktonic and soon settle in a suitable location and undergo metamorphosis into juvenile sponges. Under certain conditions, the sponge can produce buds which separate off from the parent and form new colonies. [5]
