I'm pretty sure these are salamander eggs in a small ephemeral pond in Wildman Woods (Earlham College Property). Some of the photos were taken underwater.
While participating in a hike with the 4th grade class from Paul Cuffee School, we rolled over a log along the Orange Trail and discovered a single Spotted Salamander underneath!

The spotted salamander or yellow-spotted salamander (Ambystoma maculatum) is a mole salamander common in the eastern United States and Canada. The spotted salamander is the state amphibian of South Carolina. This salamander ranges from Nova Scotia, to Lake Superior, to southern Georgia and Texas. Its embryos have been found to have symbiotic algae living inside them.
