Stage of Development: Embryo
The green anole lizard, Anolis carolinensis, is part of a diverse adaptive radiation of lizards that comprises over 400 species. For this reason, anoles serve as a model system for studying the interaction between development, evolution and ecology. This is a Stage 18 anole lizard embryo that was near-hatching. It has bone, cartilage, well-developed eyes and lamellae toe pads. Seventy still-developing vertebrae are present along the dorsal aspect of the embryo.
The author would like to acknowledge Minami Tokuyama for collecting the egg.
