How crocodile and snakes eat their food?

Crocs don't use their teeth for chewing but rather to grip their prey and they just toss it to the back of their throats and swallow it down. If venomous, the snake will bite their prey, envenomate, kill it, swallow it down whole. If nonvenomous, they would either constrict their prey and swallow it down or just bite and wait for it to stop struggling and swallow.
