Needed to add Zoa Warning...
Palytoxin is an incredibly complex marine natural product containing 71 stereochemical elements. Palytoxin, isolated from soft coral (most notably, zoanthids), is considered to be one of the most toxic non-peptide substances known, second only to Maitotoxin.
Typical symptoms of palytoxin poisoning are angina-like chest pains, asthma-like breathing difficulties, tachycardia, unstable blood pressure, hemolysis (destruction of red blood cells), and an electrocardiogram showing an exaggerated T wave. The onset of symptoms is rapid, and death usually follows just minutes after.
