Are There Any Vegetarian Snakes?

Snakes are an important part of the ecology, like anything else. In parts of Southeast Asia where they've collected lots of snakes for the snake restaurants, they do have big rodent problems because the main predator of the rodents has gone. They're very chemo-sensory and that's their primary sense. And so if it smells like a rodent, it is a rodent. There was also some news research that came out recently where they've now found that snakes appears to be able to hear sound through the air. Whereas previously we thought they detected it through their jaw on the floor.
