Massive form of Yellow sponge (Cliona celata). Large oscules with raised rims are found along the tops of the ridges. It often forms a thick plate-like structure standing on its edge with large specimens growing up to 1 m across and 50 cm high. The surface of this stage is evenly covered by tuberculate inhalant papillae. The massive form develops when the sponge has outgrown its habitat, or when it has completely filled crevices in calcareous rocks into which it cannot bore. Cliona celata is the only excavating sponge in NW Europe developing the massive form. Filmed underwater in Pembrokeshire, Wales, UK. | |
