Snakes that have just eaten are more likely to strike a predator or stimulus than snakes that do not have a full stomach. Snakes that have just eaten a large animal are less mobile. [19] Another factor that controls the antipredatory response of the garter snake is where on its body the snake is attacked.
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.
Garter snakes have been found to be one of the few species of snakes in the world to be both venomous and poisonous; both, however, are medically insignificant to the point that even affecting a human baby would be unlikely. Their poisonous aspect is only because of their diet, which consists of poisonous frogs.
Snakes are thought to have evolved from either burrowing or aquatic lizards, perhaps during the Jurassic period, with the earliest known fossils dating to between 143 and 167 Ma ago. The diversity of modern snakes appeared during the Paleocene epoch ( c. 66 to 56 Ma ago, after the Cretaceous–Paleogene extinction event ).
[1] [3] Snakes commonly involved in envenomations include elapids (such as kraits, cobras and mambas), vipers, and sea snakes. [7] The majority of snake species do not have venom and kill their prey by constriction (squeezing them). [2] Venomous snakes can be found on every continent except Antarctica. [14]
This is a list of extant snakes, given by their common names. Note that the snakes are grouped by name, and in some cases the grouping may have no scientific basis. Contents:
Why did it have to be snakes?” The reptile, christened Tachymenoides harrisonfordi, measures 16 inches long and is a pale yellowish-brown colour with black spots and a black belly.
A nail is a protective plate characteristically found at the tip of the digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals. . Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves, and horns of ver
