Pantherophis obsoletus, also known commonly as the western rat snake, black rat snake, pilot black snake, or simply black snake, [4] is a nonvenomous species of snake in the family Colubridae. The species is native to central North America. There are no subspecies that are recognized as being valid. [5] Its color variations include the Texas ...
Unlike other venomous snakes that tend to strike, release, and then track their prey, B. insularis keeps its prey in its mouth once it has been envenomated. This is thought to be an adaptation to hunting birds, as chemical tracking of prey after release—a practice used by other vipers—is much harder when airborne food sources are to be tracked.
The inland taipan (Oxyuranus microlepidotus), also commonly known as the western taipan, small-scaled snake, or fierce snake, [6] is a species of extremely venomous snake in the family Elapidae. The species is endemic to semiarid regions of central east Australia. [7] Aboriginal Australians living in those regions named the snake dandarabilla.

Snakes have a wide diversity of skin coloration patterns which are often related to behavior, such as the tendency to have to flee from predators. Snakes that are at a high risk of predation tend to be plain, or have longitudinal stripes, providing few reference points to predators, thus allowing the snake to escape without being noticed.

Increases in the amount of newt then apply a selective pressure favoring snakes with mutations conferring even greater resistance. This cycle of a predator and prey evolving to one another is sometimes termed an evolutionary arms race because the two species compete in developing adaptations and counter adaptations against each other. This has ...
