Variety natricinae snakes simply amazing!They are found almost everywhere.This land and digging, wood and water, day and night, and not very toxic, as well as oviparous and viviparous species.This is both large (up to 4 meters) and small (up to 15 centimeters) of a snake.I wonder what snakes eat with such a diversity of species?
natricinae menu
Many of them are "specialized" on a particular meal.For example, the snake egg (oviphages) feed on the eggs of birds, swallowing them whole.If you get the egg into the esophagus natricinae snake begins to bend sharply, allowing the spikes of her vertebral crush eggshells.All of the liquid contained in the egg enters the stomach and burps of shell snake through the mouth.The snakes are fed, for example, fish-eating species, probably no need to explain.There are individuals who regale only frogs or just earthworms.
What the snakes eat, does not affect the ability of their toxic.The fact, that in itself alone is absolutely safe, and generally considered non-poisonous snakes natricinae.However, that being said, exceptions prove the rule.There are some species that bite to humans can be fatal.Yet the vast majority of snakes natricinae producing poison or poisonous teeth have developed, or something similar to a tooth located in the back of the jaws, which complicates the introduction of poison in the human body.

his fellow - water snake - is found only in the south of our country, because it is very heat-loving.Its external Unlike ordinary snake - ribbed scales and the absence of yellow spots on the edges of the head.This snake is brown or greenish gray with spots scattered on the back and sides.Snake eyes water and his nostrils are directed upwards.As the name implies, these snakes are found in bodies of water, both fresh and salt water.They are excellent divers.They feed mainly various medium-sized fish.
Man - the main enemy of the snake.A lot of these snakes are killed at the hands of precisely the people.It is because we are not able to distinguish the poisonous snakes (eg, ASP) from the safe, which is really, as a result operate certain - kill innocent representatives.Remember that snakes in the house - it's not dangerous.Bright orange spots on the back of the head, as well as a fairly large panels and graceful body is markedly different from the massive snake viper.At the head of the viper is no such spots, and it is covered with small scales.
