Seawater
Just take a drop of seawater and examine it under a microscope, and you’ll be transported to a world of aquatic wonder. This one might be more fun to see live. Because everything you see here is probably alive and wiggling. From diatoms and plankton to bacteria and viruses, the ocean is home to an incredible array of tiny organisms that play vital roles in the planet’s ecosystems. And the best part? These microscopic marvels come in all shapes and sizes, from delicate, spiky-looking diatoms to wriggling, amoeba-like plankton. So next time you’re feeling curious, grab a microscope and dive into the depths of the ocean – you never know what amazing discoveries you’ll make. (Smithsonian Ocean)
