FROG AMPLEXUS
These are Eastern Narrow-Mouthed Frogs (the frogs that sound like sheep). Amplexus is the mating process where the male clasps on to a female and waits for her to release her eggs in the water, and then he fertilizes them. Sometimes multiple males will hold on to one female and can even inadvertently drown her, though I've never witnessed this myself. There are lots of photos and videos of these frogs and their tadpoles on this site.
