Spider-tailed Horned Viper
The spider-tailed horned viper (''Pseudocerastes urarachnoides'') is a species of viper, a venomous snake, in the family Viperidae and genus '' Pseudocerastes''. The genus is commonly known as "false-horned vipers". The species is endemic to western Iran and over the border region with Iraq. It was originally described by scientists as ''Pseudocerastes persicus'', attributing the tail to either a parasite, deformity, or tumors. Another specimen was found in 2003. ''P. urarachnoides'' was officially described in 2006. The head looks very similar to that of other ''Pseudocerastes'' species in the region, but the spider-tailed horned viper has a unique tail with a bulb-like end that is bordered by long drooping scales that give it the appearance of a spider. (''Pseudocerastes urarachnoides'', new species). The tail tip is waved around and used to lure insectivorous birds to within striking range. Etymology The specific name, ''urarachnoides'', is derived from Ancient Greek ( οὐ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Summer
Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice. The earliest sunrises and latest sunsets also occur near the date of the solstice. The date of the beginning of summer varies according to definition, climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Etymology The modern English ''summer'' derives from the Middle English ''somer'', via the Old English ''sumor''. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with 21 June or 21 December.

Zagros Mountains
The Zagros Mountains are a mountain range in Iran, northern Iraq, and southeastern Turkey. The mountain range has a total length of . The Zagros range begins in northwestern Iran and roughly follows Iran's western border while covering much of southeastern Turkey and northeastern Iraq. From this border region, the range continues southeast to the waters of the Persian Gulf. It spans the southern parts of the Armenian highlands, and the whole length of the western and southwestern Iranian plateau, ending at the Strait of Hormuz. The highest point is Mount Dena, at . Geology The Zagros fold and thrust belt was mainly formed by the collision of two tectonic plates, the Eurasian Plate and the Arabian Plate. This collision mainly happened during the Miocene (about 25–5 mya or million years ago) and folded the entirety of the rocks that had been deposited from the Paleozoic (541–242 mya) to the Cenozoic (66 mya – present) in the passive continental margin on the Ar ...

Bulb
In botany, a bulb is a short underground stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just ''bulbs''. Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales.

Pseudocerastes Urarachnoides Tail Png
''Pseudocerastes'' is a genus of vipers endemic to the Middle East and Asia. It was originally created as a monotypic genus in 1896 by Boulenger for the species ''Pseudocerastes persicus'', but three species are now recognised: the spider-tailed horned viper (''P. urarachnoides''); Persian horned viper (''P. persicus'') and Field's horned viper (''P. fieldi''). Like all other vipers, the members of this genus are venomous. ''Pseudocerastes'' are often referred to as false-horned vipers because of the horn-like structures above their eyes that are made up of numerous small scales. This is in contrast to the "true" horned viper, ''Cerastes cerastes'', which has similar supraorbital "horns", each consisting of a single elongated scale. Mallow D, Ludwig D, Nilson G (2003).

Pseudocerastes Fieldi
Field's horned viper Mallow D, Ludwig D, Nilson G (2003). ''True Vipers: Natural History and Toxinology of Old World Vipers''. Malabar, Florida: Krieger Publishing Company, Malabar, Florida. 359 pp. . (''Pseudocerastes fieldi)'' is a species of snake in the family Viperidae. The species is native to the deserts of the Middle East. Like all other vipers, it is venomous. It was previously considered a subspecies of the Persian horned viper (''Pseudocerastes persicus''). The main differences between this species and the Persian horned viper are in scalation and venom composition. Taxonomy and etymology Formerly considered a subspecies of ''P. persicus'', most sources elevate ''P. fieldi'' to species level. The first phylogenetic study of the genus '' Pseudocerastes'', published by Fathinia et al. in 2014, shows that ''P. fieldi'' has equal genetic distance from both ''P. persicus'' and another species of the same genus, '' P. urarachnoides''.
