This would "really challenge the dogma" that vertebrates' immune systems ban such close relationships, he says.

Why only the pix of the eggs, not the TEM scans of the cells?

Transmission electron microscopy (TEM) images showed mitochondria in the salamander cells...

I wonder if that was a mistype. It isn't unusual to find mitochondria in the cells, since all eukaryotic cells have them. OTOH, finding chloroplasts in the salamander cells would be very surprising.

Also, the article overstates the significance of foreign biological material living symbiotically within the body. Many species of bacteria live on and within the body. They protect us from infection. E. coli (and maybe other species) makes vitamin K that we need to survive. What *is* significant is that the symbiotic organism is photosynthetic.

Both mitochondria and chloroplasts are thought to be ancient bacteria that took up residence inside eukaryotes. Although incapable of independent life, they still function like bacteria.

	Gods Graves Glyphs	Thanks neverdem. The embryos produce nitrogen-rich waste that is useful to the algae, which, in turn, supply the developing embryos with extra oxygen. To all -- please ping me to other topics which are appropriate for the GGG list. GGG managers are SunkenCiv, StayAt HomeMother, and Ernest_at_the_Beach
