Ecology
Oophila amblystomatis is a single-celled green algae that can only be found inside of the spotted salamander (Ambystoma maculatum) eggs. It is not present anywhere else in nature. The algae grows alongside the salamander within the enclosed egg and provides the green color that is present. The algae more specifically, in the presence of light, uses the process of photosynthesis and provides higher oxygen concentrations to the egg. However, in the absence of light, the oxygen levels are extremely low within the egg. The spotted salamander egg provides nitrogenous waste CO2 to the algae, and the algae in return provides the salamander organic carbon and oxygen. This creates the mutualistic relationship between the two.
