From what I saw, the rule of thumb is frogs lay eggs in a big amorphous (no distinct shape or arrangement) mass. Toads lay eggs in ribbons or strings. I had similar "curly fries" in my shallows. They've since hatched out to 1/4-3/16" tadpoles .. or toad-poles as my family likes to call them. I don't see any difference between tadpoles of frog or toad. Time will tell as they start to sprout legs. Some of my 2-4" tadpoles have the ridges down the body inline with eyes though. Starting to see features.
