Sabellaria spinulosa Reefs

Habitat: Sabellaria spinulosa Reefs

Description: The tube‐building polychaete Sabellaria spinulosa can form

OSPAR Regions where it occurs: I, II, III, IV, V

dense aggregations on mixed substrata and on rocky habitats. In mixed substrata habitats, comprised variously of sand, gravel, pebble and cobble, the Sabellaria covers 30% or more of the substrata and needs to be sufficiently thick and persistent to support an associated epibiota community which is distinct from surrounding habitats. On rocky habitats of bedrock, boulder and cobble, the Sabellaria covers 50% or more of the rock and may form a crust or be thicker in structure. In some areas, these two variations of reef type may grade into each other. Sabellaria reefs have been recorded in depths between 10‐50m BCD or more.

OSPAR Regions where under threat and/or in decline: II, III
