The dewlap is an extendible flap of skin ordinarily folded under the throat of a lizard. Lizards, particularly those in the genus Anolis, extend their dewlaps during interactions with conspecifics (their own species), other lizards, and potential predators. Dewlap extension is effected by movements of elements of the hyoid apparatus. This was paraphrased from research material held by the Department of zoology, University of Tennessee.

Why do lizards do push ups?

Lizards work out for the same reason a guy at the gym might: as a display of strength. And with lizards, as can be the case with men, the push-ups also mean "get out of my territory." And a new study finds some lizards make a morning and evening routine out of the displays. Four species of male Jamaican lizards called anoles greet each dawn with vigorous push-ups, head bobs and a threatening extension of a colorful flap of skin on the neck. They repeat the ritual at dusk.

Why does your throat make weird noises when you yawn?

When you yawn, your throat and vocal cords stretch and relax, which can create unusual sounds. This occurs due to the movement of air through the vocal cords and changes in pressure in the throat. Additionally, the presence of mucus in the throat may contribute to these noises. The combination of these factors leads to the characteristic sounds you hear during a yawn.
