Dewlap - flap of skin under throat of many lizard species, including the Greater Earless lizard, above. Possibly a power display, but herpetologists don't know for sure.

Gravid - pregnant, carrying eggs (in this case) or young. Gravid Greater Earless lizards have more orange on their sides and under their throats. Compare the 'groin bars' in the female to the male above. The bars are much lighter, and she's not nearly as blue. As always, click on the photos for larger views.
Be sure to check out the Tucson Herpetological Society's (relatively) new website, especially the 100-Mile Circle. Consider becoming a member. They've got some great t-shirts! (And more : -)
