Snakes are carnivorous. That means that they eat other animals. Snakes do not have the right kind of teeth to chew their food so they must eat their catch whole.
So snakes can get their food in different ways:
1. through their fangs with poison that paralyzes their prey:
Poisonous or venomous snakes inject poison or venom into their prey. This starts the digestive process even before the snake swallows that food.
2. by swallowing their prey whole:
Their jaw is structured in such a way that it allows the mouth to open wider than their own body in order to swallow their prey whole.
Once swallowed, the muscles of their body and their hook-shaped teeth help push the food toward the stomach. The food is then digested over a long period of time
3. by wrapping themselves tightly around their prey:
The snake will then wrap one or two loops around the prey, forming a constriction coil. The snake will monitor the prey's heartbeat to ascertain when it is dead.
So the correct options are 1,2 and 3
