Tadpoles Galore!

Shortly after we purchased our land we rented a dozer and in addition to digging our daylight basement, we dug what may someday be a pond. The "pond" does hold water - a foot or two at least. Our son went down today to do some wading and called me over to look at the tadpoles . . . this picture only shows a SMALL portion of them. I would estimate that we saw at least a thousand tadpoles total - quite possibly many more. I don't know what the survial rate is for a tadpole - nor how many eventually turn into frogs, but I have a feeling we'll be hearing plenty of frogs later this summer. Do you know anything about tadpoles? Feel free to post a comment and share what you know with us . . .we're naturally curious.
