When you think of bees, you probably don’t think of single-celled eukaryotes. What could an insect have in common with, say, a ciliate?

In this video, we explore the fascinating world of protozoans, animal-like protists that are grouped by their unique modes of movement. These diverse protozoans exhibit various structures and behaviors, highlighting the incredible...

Peritrich Ciliates Masters of Long-Range Snacking

The big Roomba of the microcosmos is fascinating to watch as it lives its sink or swim life.

It’s not technically a colony. Think of it more as a community of like-minded individuals. And today, we are going to join them.

Suctorians The Ugly Duckling of Ciliates

This week, we're diving back into the world of Stentors to find out what humans and Stentors have in common!<br/>

It's time to meet a single-celled organism that is bigger than a tardigrade! We'll learn how Stentors reproduce, why they look like trumpets, and why some of them are just SO BLUE!

To study organisms at the genetic level, we need their DNA. Which means that we need to be able to wade through all the bits and pieces lying within their tiny bodies to pick out something even tinier—something we can’t just dig out with...

You’ve heard those worm horror stories, right? Stories of painful stomach cramps or diarrhea or nausea that eventually turns out to be caused by some worms that have taken up residence in someone’s intestines. It’s so terrifying and wild...

Every experiment has to start somewhere. This one began with a container full of dying microbes, and the five cute, pink ciliates called blepharisma that James, our master of microscopes, accidentally turned into a group of cannibals.

From our vantage point, as relatively large organisms, it can be easy to overlook the microcosmos, because it’s simply too small to see. It floats in front of our eyes at all times, and yet we cannot make out details until we turn to...

The ciliates we’re going to talk about today are kind of…frustrating. At this point in our journey, we’ve gotten used to the fact that the microcosmos is an indecipherable mess at times, filled with organisms that look like each other,...

Our oceans and lakes are filled with copepods, a myriad of small crustacean species that might float as plankton or infect other creatures1. And as they’re living in whatever manner best suits them, some copepods—like our friend...

If you were a protozoan, how would you zoom zoom zoom all around the microcosmos? From false feet to microtubules, find out how these single-celled eukaryotes make their way through the universe.

How do stentors make more stentors? Does Paramecium reproduce sexually or asexually? Find out on this week's journey as we explore the ways the microcosmos reproduce!

The Schoolteacher Who Discovered 700 Ciliates

The diverse groups of microorganisms in the Kingdom Protista are illustrated in this video. Microscopic views compare the main categories of protists. the different phyla of algae are also discussed. Other terminology includes: protozoa,...

Eukaryotes that are clearly not animals, plants, or fungi belong to a very diverse and fascinating group called protists. This series of videos uses captivating video footage to illustrate organisms from tiny microscopic creatures to...
