Do lizards smell with their tongues?

The sense of smell is so powerful. Without it, we couldn’t sniff out freshly-baked muffins, stinky garbage, or smoky campfires. Some animals use their noses, others use antennae or even their feet to smell. But what about lizards? They have nostrils, but do they use them to smell? We asked lizard researcher Laura Kojima to help us answer this question.  Got a question that you need to make scents of? Send it to us at BrainsOn.org/contact, and we’ll help you sniff it out.
