Summary

Description

Stelligera stuposa is a common, mustard yellow to brown branching sponge up to 15 cm or more in height. Typically, stubby in cross-section with branches arising immediately from the basal stalk. Several branches may occur in taller specimens. It has a slimy surface and hairs of uneven length, formed by spicules, which accumulate silt. Small oscules are grouped near the branch tips and are visible underwater, which aids in identification. However, they are not visible in dead material. It produces large quantities of slime when taken out of the water.

Recorded distribution in Britain and Ireland

The majority of records occur in the English Channel and the western coast of the UK, from Cornwall to Lewis and Harris in the northwest of Scotland. Many records occur in Northern Ireland and the southwest of Ireland. Sparsely recorded in the Shetland Islands, Orkney Islands, the Moray Firth, and northeast England. 

Global distribution

Stelligera stuposa records are predominantly in western Britain and Ireland. Records also in northern France and the Channel Islands. Sparse records occur in the Aegean Sea and in the North Atlantic Ocean.

Habitat

Commonly found on bedrock and boulders, but not found in harbours. Especially common in the circalittoral.

Depth range

0-140 m

Identifying features

  • Very slimy surface
  • Short stubby branches
  • Bristly, uneven hairs

Additional information

Similar in appearance to Raspailia hispida which fit within the size range, but Raspailia hispida is typically taller and more branched. Microscopic examination is required to differentiate between larger species of Stelligera stuposa and smaller species of Raspailia hispida (Bowen et al., 2018). Nematode worms often live in the outer, silt-covered layers of the sponge (Ackers et al.,1992).
