The asp viper is a venomous snake of south-western Europe. It lives in warm, sunny places with dry soil, often in hills and rocky areas. Its bite can be more severe than that of the European adder, so it is important to know what it looks like.1

It needs warm, sun-exposed areas with plenty of plant cover and fairly dry soil. It is found on sunny slopes, scrubland, forest clearings, woodland edges, mountain meadows, rubbish dumps and stone quarries. In France and Italy it is often found in low mountains and hills, especially in limestone areas.1

見分け方

Average total length is 60–65 cm. Males can reach 85 cm, while females are rarely longer than 75 cm.1
The head is broad and triangular, and it is clearly separate from the neck.1
The tip of the snout is slightly but distinctly turned up.1
The tail is very short, and males are a little slimmer than females.1
The pattern on the back varies a lot. It rarely forms a clear zigzag, unlike the European adder.1

よくまちがえられるのは： The European adder (Vipera berus) is a close relative. The asp's back pattern rarely forms a clear zigzag, as the adder's often does. Bites from the asp can be more severe than those from the adder.1

毒パワー

かむ

かむときに、毒が牙や歯から出るよ。

その毒（かむ・刺す毒）はどうなるの？

Its venom causes rapidly spreading, severe pain, followed by swelling and skin discolouration. Severe bleeding and tissue death can happen within a few hours. Vision may be badly affected, and in some cases victims developed breathing and swallowing difficulties and paralysis of the bitten limb.1

人にとってどれくらい危険？

人への危険: 深刻かまれたらお医者さんへ。死ぬことはとてもまれだよ。

About 4% of untreated bites are fatal. In Italy, this species causes 90% of snakebite cases and is the only snake in Italian mountains that can be potentially lethal. Its bites can be more severe than those of the European adder.1

データ

Ancient writers named the snake that supposedly killed Queen Cleopatra as an asp. Experts think a cobra would have been too big, over 5 feet long, to smuggle in a basket.1

In the past, the word "asp" was used to mean any venomous snake.1

In 2006, a number of these vipers were found in a wooded area near Poortugaal in the Netherlands. The species is not native there, so it was probably released or escaped.1

Asp vipers have been found at over 2,100 m above sea level in the Pyrenees, even though they are not strongly linked to high altitudes.1

The venom yield is relatively low. One study recorded a daily extraction of 9–10 mg.1
