24 week old Marbled Salamander [Ambystoma opacum] larva with newly hatched Wood Frog tadpole [Lithobates sylvaticus].Also picture Spotted Salamander egg and approximately 14 days old embryo [Ambystoma maculatum].You can clearly see the developing eyes and spine of the embryo.4-13-21

Watch as a Wood Frog Tadpole hatches,breaking through the egg membrane [Lithobates sylvaticus].I knew about the symbiotic relationship between algae and Spotted Salamanders Ambystoma maculatum] in the egg and even being in the cells of the salamanders and also know to occur in Jefferson Salamanders [Ambystoma jeffersonianum].But I knew nothing about it also occurring in Wood Frog eggs.Apparently each species has a different algae-really amazing to think that in each species has it's own algae growing,not only inside the egg but inside the cells of the host creature.And that one another seem to depend on each other for their survival.
