Dangerous snake in trailers of Camp Liberty

Dangerous snake in trailers of Camp Liberty

NCRI - On Sunday afternoon, April 8, Liberty residents faced a big and dangerous snake more than 2.5 meters long, in one of the section 2 trailers (Photo is attached).

The snake apparently has entered the trailer through the holes on the floor and has caused grave concerns among the residents. Prior to this, some dangerous snakes were seen in the camp on February 26.

Contaminations of the area, worn out trailers, lack of the necessary facilities for environment spraying and upcoming of the hot season, increase the risk of vermin and harmful creatures in this camp.

The Iraqi government prevents any reconstruction or repairment of trailers which have been extremely worn out throuout the years, in violation of the Memorandum of Understanding (MoU) signed with the United Nations. It also prevents entry of the materials needed for spraying insecticides that is substantially essential in Iraq.

The Iranian resistance draws attention of the international community to the inhuman blockade imposed on Camp Liberty and the lack of required standards of hygiene as well as obstructing the minimal reconstruction work in the camp. It also calls for immediate intervention of the UN and the US to end these restrictions.

Gopher snake

Gopher snake

Gopher Snakes vary greatly in coloration. They are usually very heavily marked, with red or orange shaped blotches at the front of the dorsal surface and black, square blotches at the rear. In the middle of the body, there is a gradual transition from one type of marking to the other. The background color is usually yellow, red, orange or brown, although some animals from the northern part of the region are significantly darker. The Cape Gopher Snake's head is usually free of markings, although they may exhibit shading from dark orange to yellow or white. The head is narrow with tall lateral surfaces that end in a square at the dorsal surface. The neck is thinner than many snakes of the same family. Cape Gopher Snakes usually average between 36 and 66 inches, or 91.5 to 168cm, in length.

 



Two varieties of Cape Gopher Snake exist in captivity. These are the "normal" variety, in which breeders have encouraged the orange and red colorations, and the "hypomelanistic" variety. The second variety has been so named by the black pigmentation at the front of the body that has been greatly reduced.

The Glossy snake is named for its slender smooth skin. They normally enjoy the sand but can be found elsewhere. They eat small mammals, birds, lizards, and other snakes. They are not poisonous, but kill their prey by constriction.

Banded sand snake

Banded sand snake
Picture

Banded sand snakes (Chilomeniscus cinctus) are primarily
thought of as dwellers of low desert sandy soils, usually associated
with creosote bush. However, the Peterson Field Guide to Western
Reptiles and Ampibians (Stebbins 1985) also includes as habitat
“sandy-gravelly washes and arroyos in rocky uplands (paloverdesaguaro association), and thornscrub habitats in Mexico.” Given
elevation ranges are from sea level to 3000 feet (910 m). In this
note we describe 2 banded sand snakes found in rocky foothills of
the Rincon Mountains, Saguaro National Park, Pima County,
Arizona at elevations of 3871 feet (1180 m) and 2880 feet (878
m).
The first record (1180 m) was from the south side of the
Rincon Mountains on a hiking trail on 12 December 2000. The
animal was active on the surface and a photograph was taken by
EZ (Figure 1). The area was dominated by perennial shrubs
including goldenweed (Ericameria larissafolia), catclaw acacia
(Acacia gregii), and honey mesquite (Prosopis velutina) but was
not associated with a wash or arroyo.

Common Name: Russell's kukri, Streaked Kukuri SnakeSize: maximum of 50 cmsNon Venomous Snake

Appearance: The Variegated kukri is a thin slender snake. It shows considerable colour

Distribution: India (Maharashtra ), Pakistan, Sri Lanka, S Turkmenistan (SW Kopet-Dag), E Iran, Afghanistan

In general most snakes species show some amount of variation in colour and markings, however Oligodon taeniolatus seems to be a master of variation. It takes a trained eye to identify and distinguish separate species, using scale morphology and scale counts to confirm the identification

Prairie Kingsnake

Prairie Kingsnake
