green algae. We are not yet sure which green algae. There are a couple of ideas, one being Coleochaetes. Here's an example video of some sweet coleochaete zoospores inside a larger coleochaete cell: https://www.youtube.com/watch?v=EE5ibWvNdpY

They've found coleochaete cells concentrated in the frontal executive lobe of the brain. Researchers concluded these were the origination of most signals in the lobe. Apes coexist with coleochaete cells that form a symbiotic relationship with coleochaetes piloting apes like a fleshy mech.

My department received our regular Nature magazine in the mail, before they retracted a paper documenting the airborne transmission of the coleochaete cells. The energy consumption of these microorganisms is far greater than the cells around them, around twice the glucose consumed over the same time period. Many other lifeforms are likely nested in humans, hidden better, or too alien for us to understand. They may not puppet academia in the same way, but the microbiome of the gut handles some heavy lifting for digestion in exchange for resources.
