I know for an absolute fact that they are bull frog tad poles.
They jump out really quick and look like a thumb just sticking out of the water or a head of a turtle.

You my friend have hundreds of bull frog tad poles. I have seen this in a small pond and they will seem like they are jumping together as a group.

Cheers Don.
