Daniel Stoupin filmed this amazing short about the hidden, microscopic, life in a pond.

Stoupin writes; We don’t need to dive into the deep ocean to find the most unusual lifeforms. This short clip is a journey into a bizarre world of microscopic inhabitants of pond water.
You will see water fleas, bryozoans, water mites, mayfly nymphs, ostracods, and, of course, hydras. They jump, crawl, and float in a completely alien environment filled with mesmerizing algae and bushes of ciliates on stalks.
