Comprehensive Description

Description

 Ciocalypta penicillus forms an encrusting cushion, usually about 10 cm in diameter, with a rough upper surface. Firm, but flexible, pointed, conical projections or digits grow upwards from the base. These projections are about 5 cm high and 0.5 cm wide. The cushions are brownish or whitish-yellow in colour, while the digits are usually translucent.The basal cushion is often covered by sand or gravel so only the digits are visible.

Description

The form of this sponge is very characteristic, it consists of a basal cushion buried in sand or gravel, from which project large conical, translucent papillae. The surface of the papillae has a glassy, translucent appearance, through which vertical spicule fibres can be seen. A central core runs the length of the papillae, this is usually conspicuous in living material. The walls of the papillae are thick and robust with a roughened texture. May be confused with Polymastia species, especially Polymastia penicillus. However, large conical papillae with a translucent, glassy appearance and visible central core are characteristic of Ciocalypta.

This species is very characteristic of, and appears to be restricted to bedrock/sediment interfaces, where upward facing bedrock or large boulders are overlain by clean coarse sand or gravel. It is usually found in the circalittoral zone in areas exposed to moderately strong wave action or tidal streams.
