Wow. This is incredible. Captured by high-definition microscopy, the footage shows the buzzing world and slimy life inside a single drop of pond water. It's completely alien, it's unnerving and it makes your stomach turn itself inside out. There are brown flatworms, Medusa looking nematodes, starfish-like hydras 'defecating' and more oozy organisms.

The video was filmed by Peter Matulavich from Ohio and he examined a drop of pond water that's only a couple of millimeters wide. After watching this video, I'll never forget how much life can fit into something so small. Related, I don't want to dip my toe in a pond ever again. [Barcroft TV via Laughing Squid]
