I found this lizard on the trunk of a large weeping willow tree. She looks fat because she is full of eggs. Instead of pregnant, you would say she is gravid. She will lay up to 11 eggs about 4 times a year. Interesting fact: male texas spiny lizards will compete with each other for territory by having a push up contest. They will each continue to do push ups until one gives up and goes away.
