Maybe 2 1/2 inches long.
I get toad tadpoles every year, these are different.
I usually buy tadpoles from a local pet store in the late spring or early summer (which I did this year). Those purchased this year have turned into small frogs.
For the past number of years I've heard the mating call of a green frog (but have never seen him), but have never gotten tadpoles from him.
He must have mated this year.
