Its venom contains a high concentration of the enzyme sphingomyelinase D, which causes both local and whole-body effects. Symptoms usually take hours to appear. The bite starts with severe pain, redness, swelling and blisters, and in more severe cases the skin tissue can die. Whole-body effects can include damage to red blood cells, heart problems, low blood pressure, kidney failure and severe bleeding.1
