“The Spotted Salamander lives in symbiotic relationship with algae. They were found in embryos of the animal. The salamander’s embryos are found in clear colored eggs, laid by the females on the underwater plants, close to the surface, so that the light can reach them.It seems like green algae help embryos get much-needed energy for growth and development from sunlight, while providing an extra source of energy (this, in turn, increases their chances of survival). Spotted Salamanders are the highest developed animal species and the only ones among all vertebrae, that can directly benefit from photosynthesis. Usually, the immune system of highly developed organisms will prevent such symbiotic behavior.”
