The asp viper (Vipera aspis) is a venomous viper species found in southwestern Europe. The specific epithet, aspis, is a Greek word that means "viper."
The European green lizard (Lacerta viridis) is a large lizard distributed across European midlatitudes from Slovenia and eastern Austria to as far east as the Black Sea coasts of Ukraine and Turkey. It is often seen sunning on rocks or lawns, or sheltering amongst bushes.
