The Chaotic Life of Seashore Ciliates

Sometimes we come across microbes that we just can't learn much about, or that don't fit into a larger story. So, this week we're sharing a few of those mysterious microbes with you.

Arugulus sure know how to get under a fish's skin, literally. Fish will actually throw themselves out of the water to get an Aruglus off of their side.

“But wait!” you might be saying to yourself. “How can an organism be photosynthetic and so afraid of oxygen? Doesn’t photosynthesis create oxygen?” And yes, you would be correct—most of the time...

It may not be the super rare tentacled ciliate we were looking for, but it's still a really cool super rare tentacled ciliate!

When James first saw these bacteria, all he knew is that they came from a sample taken from a Portuguese beach. And on the slide, the bacteria were swimming in a stark line. And that gave James an idea. He took out his phone and opened...

This is a world where microbes are both residents and food, which means that occasionally, we’ll have to spend our time together watching organisms, whose bodies are fractions upon fractions upon fractions of a millimeter in size, turn...

The family Spathidiidae is made up of around 20 genera, which encompass around 250 known species. And there’s a lot of variety in the Spathidiid family to sort through.

We’re starting this episode out with a question that we’re never going to have a good answer for: how many cells do animals have? How could we ever hope to count all those cells in each of those animals? And how could we even begin to...

Somewhere around 470 million years ago, something happened that shouldn’t have been particularly striking. An algae found its way onto land. This algae turned the lands of this earth green, altered the chemistry of our atmosphere, and...

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...

We’ve spent most of our journey through the microcosmos seeking out the organisms that are too small to see with just the human eye. The bacteria, the ciliates, the tardigrades. Part of what makes them so exciting to find is that they...

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...

As animals, we owe a lot to the single-celled organisms that came before us. These are the organisms that laid the chemical groundwork for how we live, from the DNA and proteins within them to the molecules they released into the...
