Watch Ferns Get Freaky

Season 11 Episode 5 | 3m 44s | CC

Look at the underside of a fern leaf. Those rows of orange clusters aren’t tiny insects; they’re spores waiting to be catapulted away. Once a spore lands, it grows into a tiny plant, from which fern sperm swim away, searching for an egg to fertilize. Think of *that* next time you’re hiking in the forest.
