And lastly here is one championing bloom-forming conditions for phytoplankton!

Another one of the chemosensory behavior of plankton.

We also learned about bacterio(plankton) and how their chemosensory ability to detect sources of food and adjust their random run and tumble movement to take advantage of it.

Another one on the non-intuitive flow at Low Reynolds numbers

One thing we learned about is the fluid dynamics of Low Reynolds numbers (such as very thick boundary layers) that plankton have to deal with to feed and move
