Hexactinellid sponges require a hard substrate, and do not anchor to muddy or sandy sea floors. [6] They are found only where sedimentation rates are low, dissolved silica is high (43–75 μM), and bottom currents are between 0.15 and 0.30 m/s. [5] Dissolved oxygen is low (64–152 μM), and temperatures are a cool 5.5-7.3 °C at the reefs. [5]
