This is Twirly. She is our Veiled Chameleon, and I wanted to talk to you a little bit about chameleons today. They're really neat!   She has this amazing ability to change the color - the pigment - of her skin. And, you can see she has some brown spots now. She gets darker when she's a little bit more, you know, reserved or scared. When you feed her, you can see she gets so happy.    Perfect shot!    So, you can see that she's going to change to this bright green color when she gets happy and she gets happy when she gets fed.   So, these ballistic tongues that chameleons have are really quite amazing. They carry the- the weight and the muscle in the front of their tongue and that's going to propel the tongue out, incredibly fast and pretty powerful too. When they hit their prey, it's going to expand around that prey and it's going to stick. Basically, have the prey stick to it as they bring it back into their mouth.   So when they pull that food back into their mouth, they're going to automatically close their eyes to protect them in case anything comes winging back and tries to grab onto their eyeball.    Chameleons actually have taste preferences. They have taste buds on those tongues, which is really cool. Because Twirly here actually prefers worms or meal-worms over crickets. She has, like, a line of 10 crickets sitting in here, which she doesn't want to eat.   Twirly got really upset because I wasn't feeding her enough worms. Yeah!    So she has these dark green spots all over her and that tells me that she was upset for some reason.   Chameleons take longer to change the pigments in their cells because they do it chemically instead of structurally. So it's going to take her just a little bit longer than, say, cephalopods.    Twirly is showing us that she is really mad. She has those incredibly dark spots on her and she is just basically patrolling her territory, telling us, "Hey, this is my territory. You stay away from me and get out."    All right, Twirly, we'll go ahead and leave you alone.   If you think Twirly is really cool and you want to learn more about awesome and amazing animals, then go ahead and subscribe to our YouTube channel.
