Hemorrhagins may be present in the venom, but any corresponding effects are completely overshadowed by the startling and serious neurotoxic symptoms. Based on the degree and type of local effect, bites can be divided into two symptomatic categories: those with little or no surface extravasation, and those with hemorrhages evident as ecchymosis, bleeding and swelling. , The saw-scaled viper (Echis carinatus) is small, but its unpredictability, aggressive temper, and lethal venom potency make it very dangerous.  The LD50 in mice is 0.47 mg/kg and the average venom yield per bite is 18 mg (dry weight of milked venom) according to Meier and White (1995).

Without medical treatment, symptoms rapidly worsen and death can occur rapidly after a bite due to respiratory failure. Its venom consists mostly of powerful neurotoxins which induce muscle paralysis. In the first half of the 20th century as well as in the 1950s and 1960s, 12% of treated cases ended fatally. Local tissue damage appears to be relatively infrequent and of minor severity in most cases of black mamba envenomation.
