Everyone can see the coordinates unless the taxon is threatened.
Obscured
Public coordinates shown as a random point within 10KM of the true coordinates. True coordinates are only visible to you and the curators of projects to which you add the observation.
private
Coordinates completely hidden from public maps, true coordinates only visible to you and the curators of projects to which you add the observation. Observations with private coordinates will still be used to verify place check lists.
Description
A snake, most likely some juvenile specie. I am not sure what specie was it belongs, though pattern is very close to vipera lebetina obtusa but no any other lebetina-like details are observed.

This is a young Hemorrhois nummifer. It is closely related to Hemorrhois ravergieri. Hemorrhois species often look alike to sympatric vipers. Also, this snakes have somewhat toxic saliva, which may cause local inflammatory response in human.

Hi Tigran,
At the beginning I has noted this as nummifer as well, but in days at zoo saw a coluber ravergeri and its appearance changed my mind :)
Can you share the details which made you sure that this one is nummifer?
I would like to learn
There is a lot of confusion about these species. Mainly due to variability in both species. Differences in distribution:
In Armenia Hemorrhois ravergieri is known from higher elevations and also from Kura river basin (North-East Armenia). In Araks valley it often occupies the same habitat with Montvipera raddei, and as a rule does not encounter at elevations below 1400 m. a.s.l. My guess is that at lower elevations it is too hot and dry for this species.
Hemorrhois nummifer is known only from the foothils of Araks valley anf meghri. In general, this snake is sintopic with Macrovipera lebetina obtusa. Although, sometimes it may occure at levations up to 1600 m, typically this snake preferes canions in the semidesert zone.
Coloration and pattern:
Armenian Hemorrhois ravergieri always has very distinct dark-chocolate pattern with white outline on the grey to brown background check the link: http://www.herp-am.narod.ru/Gallery/hrph.htm Mainly due to darker background, baby H. ravegiery are not that bright colored as adults, but pattern is always chocolate or coffee color.
In contrast Hemorrhois nummifer as an adult is overall grey to light brown snake. The pattern of Hemorrhois nummifer is diffused. As a rule it does not have white outlines. Although some juveniles (mainly females) can be exceptionally bright colored (check the link http://www.herp-am.narod.ru/Gallery/hnph.htm), and often get confuzed with H. ravergieri, they never have well formed white outline of the pattern saddles. With age this contrast washes away, and snake becomes less or more uniform grey to light brown.
There are also some differences in the midbody (23-25 in nummifer, 21 in rvargieri), ventral and subcaudal scale counts as well as in anatomy of hemipenes. But I prefer to consider scale counts along with coloration and pattern details, but nor rely on any single scale count variable.
Thanks a lot for the detailed answer!
Saying the truth I am a pure amateur in this area. And almost all of my knowledge about snakes I got from web. And honestly said I am familiar to the http://www.herp-am.narod.ru and I can confirm that it is the best resource about Armenian reptiles I have met in web.
Probable about 70 % what I know now I learned there.
Your arguments are very strong, I am now more inclined that the mark in zoo "Hemorrhois ravergieri" was just wrong :)
I will change back my assumption
Thank you Artem :).
By the way, now is a right season for hepring in Armenia. Do't waste your time, go hiking and if you see anything, please take photos and submit your observations. Also, feel free to encourage others to join Inaturalist, or our Project. As you see this is a right place to learn about wildlife. On the other hand, the more put their passion into the collecting, documenting and publishing the data about wildlife, without damaging it, the more secure the wildlife is going to get as a result :)
The data quality assessment is a summary of an observation's accuracy. All
observations start as "casual" grade, and achieve
"research" grade when
the iNat community agrees with the observer's ID, where an "agreeing"
identification is one that matches exactly or is of a child taxon of the
observer's ID. For example, if Scott says it's a mammal and Ken-ichi
says it's Homo sapiens, then Ken-ichi agrees with Scott.
the observation has a date
the observation is georeferenced (i.e. has lat/lon coordinates)
the observation has a photo
Observations will revert to "casual" grade if the above conditions aren't met or
the community agrees the location doesn't looks accurate (e.g. monkeys in the middle of the ocean, hippos in office buildings, etc.)
the community agrees the organism isn't wild/naturalized (e.g. captive or cultivated by humans or intelligent space aliens)
iNaturalist.org shares licensed observation data with
several data partners so your data can be more accessible to
scientists and other researchers.

could be a Zamenis as well. Picture is not good enough for a definite in my opinion.
yes thanks to note!
just got an idea to look for some alike photos in web..
it seems this can be Coluber ravergieri as well
