This section describes the environmental requirements of the five reef building species under consideration. Where possible these requirements are described specifically in relation to reef communities, but in many cases information is only available in relation to the species in other biotopes or in a more general sense.

Physical strength / fragility of the reefs is also described here, but for more general descriptions of the physical form of the reefs see elsewhere.

Sabellaria alveolata

Sabellaria spinulosa

Modiolus modiolus

Mytilus edulis
