(Pseudocerastes persicus fieldi) Field’s horned viper
There is a more pronounced difference between the two subspecies with regard to their venom. While Pseudocerastes persicus persicus’ venom exhibits strong hemorrhagic activity typical of most vipers, the venom of P. p. fieldi is unusual in that contains several fractions that show marked neurotoxic activity. No antivenin is available for bites from either subspecies. It is reported that a polyvalent antiserum does offer some protection from the hemotoxins, but none against the neurotoxic effects of P. p. fieldi venom
