How do lizards detach their tails?

Lizards are awesome creatures. Some have long forked tongues, others can move their eyeballs in opposite directions. And get this: some lizards can even drop their tails and grow new ones. But how and why do they do this? We asked lizard researcher Laura Kojima to help us find the answer. Got a question that you iguana know the answer to? Send it to us at BrainsOn.org/contact, and we’ll help you find the de-tails. See omnystudio.com/listener for privacy information.
