I took a picture of this snake in Switzerland (Geneva Area):


It looks to be an adder but cannot be sure about which species.

In Switzerland we have two kinds of adder:

  1. Vipera berus
  2. Vipera aspis

For me it looks like a Vipera berus, but all the images I saw from both species (and the variations) I cannot be sure.

amazing that you stood long enough to take a picture of an unknown snake.. I would be running my lungs out.. – The Last Word May 23 '14 at 4:29
I was at reasonable distance and with a 70-200mm it helps. But yes I recognised an adder (lightly venomous) but I know they are quiet as long you don't go next to them. – ruffp May 23 '14 at 6:49
An generally speaking, snakes in Europe tends to escape before attacking – ruffp May 23 '14 at 6:50
I'm not an expert so don't feel qualified to answer, but a bit of reading suggests to me that it is Vipera aspis because the head looks rather broad and there is no clear dorsal zigzag. – Alan Boyd May 23 '14 at 10:01

I think it's an Vipera Aspis.

from wikipedia:

The dorsal markings vary strongly, but only rarely take the form of a clear zigzag, as in V. berus.

Thanks for your answer. After searching about the repartition of both snakes around Geneva, I found these maps that confirm vipera berus is not present in Geneva area as vipera aspis is – ruffp Jul 16 '14 at 22:47
