Does eating a poisoned prey harm the snake?

Some snakes have better vision at night, and others see better in daylight. Snake's skin does not grow, so they must shed their skin regularly, having grown new skin underneath. All snakes are carnivorous, which means meat-eating.

Snakes must find prey, and they eat whatever they can catch. Snakes cannot chew, so they swallow their prey whole. They are able to disconnect their jaws so that they can open their mouths very wide to swallow large prey.

Snakes have different ways of catching prey. Some snakes kill their prey with poison, called venom. These are venomous snakes.

Some snakes kill their prey by suffocating it. These are constrictors. Some snakes swallow their prey alive and whole.

Venomous snakes have a couple of long teeth called fangs. The fangs are hollow and fold back when not in use. They are used to inject poison when the snake bites its prey.

Constrictors coil around prey and crush it to death. Most snakes hatch from eggs that have a leathery shell. Snake eggs are rather oblong in shape.

The female lays them in a moist, warm place: the warmth of the sun and the earth control the incubation. It may take up to 60 days for the eggs to hatch. Some snakes give birth to live young, the eggs having developed inside the mother's body.
