An older snake may shed its skin only once or twice a year, but a younger, still-growing snake, may shed up to four times a year. [18] The discarded skin gives a perfect imprint of the scale pattern and it is usually possible to identify the snake if this discard is reasonably complete and intact.
The skin of snakes is highly sensitive to contact, tension, and pressure; they are capable of feeling pain. [65] An important function of the skin is the sensation of changes in air temperature, which can guide the snakes towards warm basking/shelter locations. [66] All snakes are ectotherms. To maintain a stable body temperature, they exchange ...

Since most venomous snakes move about during the dawn dusk or night, one may expect more encounters during the early morning or late afternoon, though many ...
The Common death adder (Acanthophis antarcticus) is a highly venomous snake species with a 50–60% untreated mortality rate. [87] It is also the fastest striking venomous snake in the world. [88] A death adder can go from a strike position, to strike and envenoming their prey, and back to strike position again, in less than 0.15 seconds. [88]
In each of these populations, the snakes exhibit resistance to the toxin and successfully prey upon the newts. Successful predation of the rough-skinned newt by the common garter snake is made possible by the ability of individuals in a common garter snake population to gauge whether the newt's level of toxin is too high to feed on.
The scales have light-colored keels and sometimes yellow tips that form a series of 30 or more light crossbands or chevrons. On the tail, there are 10 to 19 chevrons: not always clearly defined, but usually present. The ventral edge of the dorsum has light spots in pairs. An interstitial black color is visible only when the skin is stretched.

Antivenom is manufactured by the Japan Snake Institute [8] and is an effective treatment for R. tigrinus bites, [9] [10] but is an unapproved drug. The venom is highly hemorrhagic. [11] [12] While the term "poisonous snake" is often incorrectly used for a wide variety of venomous snakes, some species of Rhabdophis are in fact poisonous as well ...
