Capitella capitata represents a complex of opportunistic polychaete species especially associated with organically enriched and polluted sediments (Warren, 1977; Pearson & Rosenberg 1978) where members may be superabundant. Although more widely occurring, when these species occur in high numbers and the overall species richness of the habitat is considerably reduced, the sediments are invariably anoxic and often have a very high organic load. Nematodes, Tubificoides spp., Pygospio elegans and Malacoceros fuliginosus may also survive in this habitat, but rarely in anything but comparatively low numbers. This biotope may also occur to some extent in the intertidal. IMS.Cap may become established as a result of anthropogenic activities such as fish farming and sewerage effluent but may also occur with natural enrichment as a result of, for example, coastal bird roosts. Capitella capitata may also occur in high numbers in estuaries (see IMU.CapTub), but this may be a result of competitive refuge rather than organic enrichment (Wolff, 1973).
