"Ants solving a geometric problem and it's amazing."

This is a great example of 'emergent phenomenon':
- None of the ants understand the problem they're solving.
- None of them can see the whole shape.
- A series of small decisions or rules add up to something with a new layer of complexity.

One of my favorite radiolarians. I call it a "little hat", but I guess it is probably Eucecryphalus sp. Here are two examples from Bermuda (Atlantic) and Puerto Rico (Caribbean). Exquisite little #protistsonsky. I love seeing these forms in different regions of the Oceans. #protistaday #marinelife

An image of a radiolarian from the Carribean Sea off of Puerto Rico, likely from the genus Eucecryphalus. Looks like a little glass hat.

The rhizarian testate amoeba Euglypha rotunda eats its co-cultured bacteria, but it will also chow down on GFP E. coli. One day I'll use these vids to measure digestion rates. @thealgaeman.bsky.social another answer to what they eat! #protistaday #protistsonsky

Palpitomonas: the movie. I like this blurry little video because it shows the cryptistid Palpitomonas with its two absurdly long flagella beating with two different patterns. I imagine it as a pianist playing different parts with each hand. #protistaday #protistsonsky

The rhizarian testate amoeba that I shared yesterday makes its shell out of intricate, self-constructed glass scales. Other testate amoebozoans in the same environment make their shells out of debris (left) or food (right). These are interesting examples of convergence! #protistsonsky #protistaday

Today's #protistaday is a scan through a multinucleated Acantharian cell from here in the Gulf of Maine. All of the larger Acantharians I've looked at have multiple nuclei like this... need to take a look at/stain the teeny "baby" ones to see how these structures develop! #marinelife #protistsonsky

Not a fish or a dragon scale, but a single cell of a #protistsonsky. This rhizarian testate amoeba creates perfect tiny glass scales to build it's shell. From a peat bog. #protistaday.
