[Note Guidelines] Photographer's Note
Cerastes cerastes is a venomous viper species native to the deserts of Northern Africa and parts of the Middle East. They often are easily recognized by the presence of a pair of supraocular horns, although hornless individuals do occur.
Arid north Africa (Morocco, Western Sahara, Mauritania and Mali, eastward through Algeria, Tunisia, Niger, Libya and Chad to Egypt, Sudan, Ethiopia and Somalia) through Sinai to the northern Negev of Israel. In the Arabian Peninsula, it occurs in Yemen, extreme southwestern Saudi Arabia and parts of the country in Qatar where it is sympatric with C. gaperettii. A report of this species being found in Lebanon is unlikely, according to Joger (1984). Originally, the type locality was listed only as "Oriente." However, Flower (1933) proposed "Egypt" by way of clarification.
These snakes favor dry, sandy areas with sparse rock outcroppings, and tend not to prefer coarse sand. Occasionally, they are found around oases, and up to an altitude of 1500 m. Cooler temperatures, with annual averages of 20C or less, are preferred .
They typically move about by sidewinding, during which they press their weight into the sand or soil, leaving whole-body impressions. Often, it is even possible to use these impressions to make ventral scale counts. They have a reasonably placid temperament, but if threatened, they may assume a C-shaped posture and rapidly rub their coils together. Having strongly keeled scales, this produces a rasping noise, similar to Echis. They are capable of striking quickly.

A number of subspecies may be encountered in literature:
* C. c. hoofieni - Werner & Sivan, 1999 - Saudi Arabia.
* C. c. karlhartli - Sochurek, 1974 - Egyptian horned viper - southeast Egypt and Sinai Peninsula.
* C. c. mutila - Domergue, 1901 - Algerian horned viper - southwest Algeria, Morocco.

Salut Iulian
Superba! Si eu sunt pasionat de serpi dar nu prea reusesc sa-i gasesc aici in tara.
Numai bine

Dear Julian,
Impressive photo pity though, there is not enough depth of field and and the head is out of focus - i.e. the body below (the head) is in focus...

Having said this IT IS an excellent photo! I would be so excited seeing this beauty, I would have the shakes and nothing in focus!!

Additionally, at 2 p.m. - with the sun above your head - it must have been very difficult to get the exposure right with the reflections of the sun from the sand!!

Have a nice evening and a good Sunday
Best Greetings from South Africa

Hi Iulian,
a beautiful snake and with the colour of the surrounding sand the contrast is difficult. I have tryed a workshop. I hope you feel not offended.
Have a nice sunday.
Pierre

beautiful and daring shot. a great beautiful species.

Hello Iulian,

A difficult and dangerous environment like the desert against a type of viper is a great attraction.
Details, light, color and sharpness settings are also technically very successful.
Thank you for sharing.

Regards,
Mehmet
