Snakes slither by using their scales as friction hooks to latch onto rough surfaces and propel themselves. They also shift their weight around, concentrating it in a way that allows them to move. Some snakes may have individual muscle control over their scales that allows them to move rapidly.Know More
Snakes have varying methods of travel depending on their surroundings. Terrestrial lateral undulation is the most commonly used means of transportation. With this mode of locomotion, the snake moves its posterior in waves, pressing against nearby objects such as rocks, twigs and irregularities in the ground. The snake's speed varies depending on the environment.
In areas without objects to push off, such as in a sandy desert, snakes use a technique called sidewinding. The snake alternates its body sections in an up and down motion, which causes the snake to roll in a strange, sideways manner. Sidewinding is similar to lateral undulation, except that the snake only pushes off with static contact points of the body.
Aquatic snakes swim through the water, making waves that grow larger as they pass the snake's body. The snake moves forward slower than the waves pass and the waves thrust them forward. Aquatic undulation differs from terrestrial undulation, as the muscles activate differently. All snakes can undulate forward through water, but only sea snakes are capable of undulating in reverse.Learn more about Snakes
Not all snakes are venomous, but even nonvenomous snakes are subject to strike if they feel frightened or sense danger. In North America, an easy way to determine if a snake is poisonous is to look at its pupils. With the exception of the coral snake, the pupils of poisonous snakes are elliptical or slit-like, much like the eyes of a cat, while the pupils of a non-venomous snake are round.Full Answer >
Predators of snakes include large animals such as foxes, raccoons, boars and birds. In addition to its natural predators in the wild, the snake is threatened by humans. Humans hunt snakes for their venom to make serums. They also use snake skins for clothing and accessories.Full Answer >
Adult snakes shed between four and eight times per year. However, their activity level, habitat temperature and feeding frequency and amount affect the frequency of shedding. Additionally, young snakes that are rapidly growing may shed more often.Full Answer >
Snakes do have teeth. Snake teeth are highly specialized according to how the snake kills its prey. Most snakes only have one type of tooth throughout their mouths, though the size of the teeth may differ.Full Answer >
