SS.SMu.CSaMu.VirOphPmax recorded () and expected () distribution in Britain and Ireland (see below)
Temperature range preferences - 5-15°C although where this biotope occurs in shallow water may be subjected to higher temperatures.
Water clarity preferences - Data deficient
Limiting Nutrients - Nitrogen (nitrates)
Other preferences -
Seapen biotopes occur in wave sheltered sealochs and much deeper open sea suggesting that water movement, particularly being sheltered from wave action, is more important to their existence than light.
