We have noticed frog’s eggs in both of our ponds that look very different from the ones we’re used to seeing. All the eggs are in the same stage of development, but some are at least twice as large. The larger embryos are encased in their own perfectly round gelatinous sacs… each egg sac clearly defined with several grouped together like a bunch of grapes.
The eggs we usually have here are smaller… and there are loads of them this year too… but the sac around each embryo is not nearly as well defined. We have also noticed that the larger eggs are mostly resting on the surface of the water… the smaller egg masses are more submerged.
The tadpoles hatching from the larger eggs are going to be much, much bigger from day one. It will be interesting to see what type of frog they turn out to be.
