Our most poisonus snake in this part of Croatia is Ridjovka (Vipera berus) relatevely mild-poisonus and in mountains of Velebit we have two species of Poskok(Vipera ammodytes)-shorter and more venomous and longer specie.Now they feed on rats and other snakes so they can t be bad just if we leave them alone respect Reply rikib July 25, 2010 at 2:30 am C-S,
