Embryo Project Encyclopedia
The Embryo Project Encyclopedia (https://embryo.asu.edu) is an open-access digital encyclopedia devoted to recording and contextualizing the science of embryos, development, and reproduction. The collection of documents, images, and multimedia housed here serves as the Encyclopedia's permanent archive.
Jane Maienschein, ASU University Professor, Regents Professor, and Director of the Biology and Society Program, started the Embryo Project Encyclopedia in 2007 with support from the National Science Foundation.

The Southern Gastric Brooding Frog (Rheobotrahcus silus) was a frog species that lived in Australia. It was declared extinct in 2002. Once adult males fertilized the eggs of females, the females swallowed their eggs. The stomachs of the females then functioned somewhat like wombs, protecting the eggs while they gestated. Once the eggs developed into juveniles, female frogs performed oral birth and regurgitated their young.
The crystal jellyfish, Aequorea victoria, produces and emits light, called bioluminescence. Its DNA codes for sequence of 238 amino acids that forms a protein called Green Fluorescent Protein (GFP). FP is folded so that a part of the protein, called the chromophore, is located in the center of the protein. The chemical structure of the chromophore emits a green fluorescence when exposed to light in the range of blue to ultraviolet.
