Family Dysideidae, Tetilla
Common Name: Boring sponge
Cliona celata is lobular in shape with wart like projections on it surface. This species is commonly found in colonies and the portions of the colony showing at the surface have projections appearing as yellow in color. They are evenly distributed on the sponge and are inhalent and seive like. Below the surface, the Cliona celata shell may look like a honeycomb. Cliona celata is commonly referred to as the boring sponge because it bores into soft limestone, using an acid digestion technique thus forming systems of interconnecting chambers within the matrix of the substrate
The sponge can also bore as a parasite into mollusc and barnacle shells. It is common on many of the purple hinged rock scallops that we see underwater at Race Rocks.
At Race Rocks, the boring sponge is commonly found around the Rosedale Reef area. Its exhibits a biotic association with the purple -hinge rock scallop (Hinnites giganteus ) . Below is a picture of a complete rock scallop with small yellow dots where the sponge is located.
