A snake continues to grow its entire life, but its outer skin does not, so the snake needs to shed, or molt, its external skin from time to time. In Tel Aviv Universitys Garden for Zoological Research, snakes kept in terraria lived nearly 14years, fed on small vertebrates, and females laid clutches comprising 616 eggs30. [3] Many snakes previously identified as their own genera or species have been reclassified as species or subspecies in Thamnophis. Kalyaanamoorthy, S. et al. In captivity they can survive for 30 years or more. More surprisingly, later studies showed much genetic diversity between eastern and western populations of "E. sauromates", suggesting the existence of another species23,25. 9, 16571659 (2000).

As mentioned by Bar et al.30, this species is rare in the Golan and is likely threatened by increased land-use changes for tourism (e.g., the only ski resort in Israel is in Hermon), habitat degradation by military activities, overpopulation, accelerated development, traffic density, collecting, and, of course, like all Hermon endemics, by global warming. [8], Garter snakes were long thought to be non-venomous but discoveries in the early 2000s revealed that they in fact produce a neurotoxic venom. ADS Some squamates (e.g., Mediodactylus amictopholis, Montivipera bornmuelleri) directly represent endemics of Lebanon and Anti-Lebanon Mountains with the southern edge of their distribution at or around Mount Hermon30.

In RAG1, E. quatuorlineata and E. sauromates exclusively share separate alleles while E. urartica is represented by two alleles one of which is shared with the Southern Levant clade.

Snakes can strike (or reach forward quickly to grab their prey) with amazing speed. However, sea snakes have flattened tails that they use like paddles to propel them through the water, and some tree snakes are called flying snakes, although they don't really fly but flatten their body and spread their ribs to glide from tree to tree.

Despite the decline in their population from collection as pets (especially in the more northerly regions, in which large groups are collected at hibernation),[15] pollution of aquatic areas, and the introduction of American bullfrogs as potential predators, garter snakes are still some of the most commonly found reptiles in much of their ranges. 190, 231259 (2006).

Python is a genus of constricting snakes in the Pythonidae family native to the tropics and subtropics of the Eastern Hemisphere. For these purposes, we used the concatenated dataset used for ML and BI analysis (see above) and the Newick format of tree from BI analysis (MrBayes 3.2.674) following default settings of the analysis.

ModelFinder: Fast model selection for accurate phylogenetic estimates. We hypothesize that the area occupied by the ancestor of E. urartica and E. druzei sp. When we initially tested molecular clock analysis using BEAST 1.10.486, we revealed the alternative topology of E. quatuorlineata as a sister lineage to the group of E. sauromates, E. urartica, and the new clade. In NT3, one allele is exclusive for E. urartica, a second allele is shared by E. urartica, and the Southern Levant clade, and two alleles are exclusive to E. quatuorlineata. In south-central Florida, breeding occurs from June to January, with egg laying between April and July and hatching from mid-summer to early fall.
