[5] Including being found in India,[6][7] Arabian Sea,[8] Brazil,[9] North America (including Alaska, British Columbia, Washington, and Oregon[10]) Chile, New Zealand (Tasmania and Campbell Island) and the Falkland Islands.

[3] Most Scinaiaceae species produce mucilage (thick, gluey substance) mainly in the cortical layer.

[11] Several species in the Scinaiaceae family (including Nothogenia fastigiata and Scinaia hatei) have been screened for anti-viral activity (against herpes, Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B and simian immunodeficiency viruses).

Sulfated polysaccharides (xylomannans) from the red alga, have inhibitory effects.
