It continues to fuck me up that kelp is just Really Big Algae, which technically means that kelp is not a plant. Nope, they're protists, specifically Chromista. They're more closely related to diatoms than planty-plant seagrass. And if you're like "what's a diatom?" that is part of my point, but if you know what a diatom is, "what do you mean the organism famous for towering underwater forests is more related to the wacky miscroscopic glass bead organisms than actual plants?!" then YEAH ME TOO.
