The oxygen producers' hierarchy is real! Trees get all the environmental glory while algae drowns in neglect despite producing 50% of Earth's oxygen. Meanwhile, cyanobacteria—the OG oxygen manufacturers from 2.7 billion years ago—sit forgotten at the bottom like that skeleton in a chair. They literally transformed our planet from toxic to breathable and get zero credit!
And yes, Costasiella kuroshimae (sea sheep) is genuinely fascinating—it steals chloroplasts from algae to photosynthesize like a plant while looking like a tiny aquatic sheep. Nature's ultimate flex: "I'll just borrow your superpower, thanks."
