Do tarantulas suck food through their fangs?

Question

Do their fangs work somewhat like our esopagus/trachea, where one channel opens to deliver venom and another opens to recieve the juices? Do they have a mouth that they use for drinking water and "eating?"

Answer 1

Fangs are for delivering poison. Juices from the digestive glands liquefy the prey before it is sucked into the mouth by the stomach's pumping action

Answer 2

no, fangs deliver poison. The vemon breaks down the victim into a fluid, and is "drank".
