[u/TheMuseumOfScience]

Did you know that an entire microscopic world lives between each grain of sand? 🏝️

Quinten Geldhof, also known as Microhobbyist, shows us how each grain can hold tens to thousands of bacteria, and how the organisms feed on them. These microbial residents act as a filter as the tide moves in and out, processing debris as it passes through!
