Summary

Description

A tall mustard yellow to pale brown branching sponge reaching up to 35 cm in length with thin hairy branches of up to 13 cm in length. Branches may taper to points. It si found commonly in the deep sublittoral alongside other branching sponges. Typically, one to three stalks branch from the base but some may have branches that arise immediately from the basal stalk. The sponge surface is hairy or bristled (hispid) because spicules protrude from its surface. These spicules can trap a layer of silt and give the sponge a ‘dirty’ appearance. Small exhalent apertures (oscules) are visible underwater and tend to form evenly spaced rows along the edges of branches, but they are not visible when preserved. This species does not produce slime when taken out of the water. 

Recorded distribution in Britain and Ireland

Raspailia hispida is widespread on the rocky coasts of western Britain, in the English Channel, Northern Ireland and the Irish Sea, with sparse records on the east coast of Scotland in the Shetland Islands and the Firth of Forth. 

Global distribution

Raspailia hispida is widespread across rocky coastlines in south and west Britain, with scattered records from Norway, the North Atlantic and the Mediterranean.

Habitat

Regularly found on horizontal and vertical rocky bedrock, or boulders, in moderately exposed coastal areas or in sheltered areas with some tidal movement. Often found alongside other Axinellid sponges. 

Depth range

0-300 m

Identifying features

  • Yellow to brown branching sponge
  • Up to 35 cm high, with branches up to 13 cm in length 
  • 4 to 6 mm branches that taper to blunt tips

Additional information

This species can only be definitively identified through microscopic examination. In the field, it can be confused with similar species such as Stelligera stuposa but is typically taller and less branched (Bowen et al., 2018). Stelligera stuposa also produces slime when removed from the water which Raspailia hispida does not.
