Shelf Life Video: The Salamander-Algae Symbiotic Relationship

What happens inside a Salamander egg? How does the embryo interact with its environment? Find out in this video, which is another in the Shelf Life series from the American Museum of Natural History.   Scientists collect Salamander egg masses to investigate the symbiotic relationship between embryos and algae. The two organisms exchange substances that help each other to thrive in their environment.
