We've been raising a set of Cope's Gray Treefrog eggs harvested from our backyard garden pond for a month now. We were able to observe them in the egg state and watch them become small specks into what they are now, big juicy tadpoles. They still do not have any legs, but I imagine it won't be long. From our research it looks like they can take up to 60 days to fully metamorphosize.
Frog eggs just days old.
Tadpole at 1 week old.
Tadpoles feeding at 12 days old
Cope's Gray Treefrog tadpoles currently at 1 month old. Large body and tail, no legs.
