Summary

Description

A soft, fragile sponge with an even, greyish light-brown or purple-brown colouration. It has few key external identification features. The sponge varies in shape from thin encrusting patches to laterally spreading masses of interconnecting branches and finger-like protrusions with large terminal exhalent pores(the 'oscules'). The surface of this sponge consists of a network of tissues with irregular spaces which gives a "loosely woven" appearance. The oscules on this species, regardless of location, lack the raised edge found in other members of this group. The oscules are irregularly scattered about the sponge and can be from a few centimetres to up to 25 cm in diameter in larger examples (van Soest, 2000; Picton & Morrow, 2000).

Recorded distribution in Britain and Ireland

Haliclona (Reniera) cinerea is present on the western coasts of England, Wales and Scotland and throughout the Shetland Isles. This sponge is also widespread around the coast of Ireland.

Habitat

Haliclona (Reniera) cinerea is found at depths from around 10 m to 50 m. It is common under intertidal stones and in sheltered habitats with moderate to strong tidal currents. The tall finger-like form is only found in sheltered environments (Picton & Morrow, 2000).

Identifying features

  • A soft and fragile sponge with a variable morphology.
  • Can form encrusting sheets, rounded lobes, finger-like protrusions with large terminal oscules and spreading masses of anastomosing (interconnecting) branches.
  • The surface has a "loosely woven" appearance.
  • Sponge is greyish light-brown or purple-brown and coloured evenly.
  • Oscules are at the terminus of protrusions or otherwise irregularly scattered.
  • Oscules lack raised edges and range in diameter from a few centimetres to up to 25 cm.
  • This species is differentiated from others by the morphology of its spicules

Additional information

Haliclona (Reniera) cinerea is distinguished from other species such as Haliclona rosea by internal characteristics such as the fine details of spicules. The slime strands from this species are also characterizing (see van Soest, 1977 and 2000).
