See the changes in the spinal cord, eyes, external gills, color, etc., as the embryo develops. Oophila alga is visible inside the eggs. Filmed with a Sony AX100 from March 23 - April 4, 2019.
According to http://www.animalspot.net/spotted-sal...,
"Eggs of A. maculatum can have a symbiotic relationship with a green alga, Oophila amblystomatis. Jelly coating prevents the eggs from drying out, but it inhibits oxygen diffusion (required for embryo development). The Oophila alga photosynthesizes and produces oxygen in the jelly. The developing salamander thus metabolizes the oxygen, producing carbon dioxide (which then the alga consumes). Photosynthetic algae are present within the somatic and possibly the germ cells of the salamander. In two to four months, the larvae lose their gills, and become juvenile salamanders that leave the water. Spotted salamanders have been known to live up to 32 years."
