information on the biology of species and the ecology of habitats found around the coasts and seas of the British Isles

A sponge (Ciocalypta penicillus)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

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.

Recorded distribution in Britain and Ireland

Ciocalypta penicillus is found on the west and south coasts of Britain and at various locations around the coast of Ireland.

Global distribution

Ciocalypta penicillus is found from Denmark to the Mediterranean, including the Azores and Madeira.

Habitat

Ciocalypta penicillus is usually found attached to upward facing rock surfaces typically covered in clean sand or gravel but sometimes more silty sediment.

Depth range

Subtidal

Identifying features

  • Brown or whitish-yellow encrusting cushion up to 10 cm in diameter.
  • Pointed conical digits project upwards from base.
  • Basal cushion often covered in sand or gravel.

Additional information

The basal cushion is often covered by sand or gravel so only the digits are visible.
