Large up to 5.5 inches long, large girth. Subdued grayish blue with very dark blue collar area under neck. Males have vivid blue throats and under bellies. Exhibit metachromatism which is color change as a function of temperature. Cool temperatures mean darker colors. Darker colors allow for increased heat absorption from the sun.

Very large, not at all afraid. Beautiful blue markings on its neck and belly. They love to eat strawberries when we put them out for the birds!
