Sometimes you need to take your little shelled amoebas out for a walk. Rhizarian testate amoeba euglypha rotunda #protistsonsky #protistaday

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.

Crawling through the water in slow motion, the tetraflagellate green alga Cymbomonas swims across the frame with its double-breaststroke like action pulling it forward. #protistaday #protistsonsky #marinelife

A gorgeous planktonic foram from the Atlantic Ocean near Bermuda. With @blancobercial.bsky.social. Your #protistaday! #protistsonsky #marinelife

Keeping with the #symbiosky green alga from yesterday, this amazing video shows where each little algal cell is (green dots) inside a salamander embryo. The only vertebrate-alga endosymbiosis. We are still trying to understand the interaction. Light sheet microscopy. #protistaday #protistsonsky

A bunch of cells of the nasselarian radiolarian Plagiacantha arachnoides--like a group of little spiders! Plus a couple of bonus acantharians. From the gulf of maine #protistaday #protistsonsky #marinelife

Plankton tows in Puerto Rico with @micrott.bsky.social are going great! Lots of beautiful microeukaryotes and tiny animals. Today I'll share this Ornithocerus sp. dinoflagellate bc you can see it's little band of bacterial symbionts! #protistaday #protistsonsky #marinelife

Okay... #protistaday. I know this is a phaeodarian, but how does a cell evolve to build a glass mouth, teeth and all, to live inside? This is totally amazing. #protistsonsky #marinelife. With @evocellbio.bsky.social @micrott.bsky.social

Mitosis in a green alga. The cell grows until it is tetralogy, then divides twice to form 4 new haploid cells. This is one of my study algae, Oophila amblystomatis, a symbiotic green alga. #protistsonsky #protistaday

A nasselarian radiolarian with its podoconus (cone-like arrangement of long arms) out and lots of internal movement. Beautiful to see! In the water column, that cone of arms is probably oriented "up" for catching debris/prey and managing motion with the hard skeleton pointed "down" #protistaday

Is it a repeat? Sort of, but this is a radiolarian in motion! I wanted to see how dynamic the symbionts are. They mostly stay still over a couple of minutes. With @micrott.bsky.social and @evocellbio.bsky.social #protistaday #protistsonsky #marinelife

In hopes of finding lots of Carribean radiolarians today, my #protistaday image is a constellation of microscopic stars of the sea, acantharians. #marinelife #protistsonsky

A little #bogmonster #symbiosky ciliate captured by a visiting student in an agar microwell from the readily reproducible protocol by @arcadiascience.bsky.social. Look at it go! #protistaday #protistsonsky. Protocol links below.

I wonder whether I can manage a #protistaday... Seems (probably too) ambitious. I am trying to share the little things that bring me joy. Today: look at this adorable #radiolarian wondering what it is doing touching a plastic dish rather than drifting in the open ocean. #protistsonsky

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

From a large, local, and unusual, bloom of the dinoflagellate Tripos muelleri in 2023. I trapped some cells in agar microwells to see if I could catch them dividing in a long timelapse. Those wells are 250 microns in diameter: the cells are large! #protistaday #protistsonsky #marinelife

Change your illumination a bit and everything looks new! Radiolarians illuminated from the side rather than using transmitted light. I think this is mimicking a type of reflected light microscopy since there is no light passing directly through the specimens. #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
December 17, 2024 at 2:49 PM
Today's #protistaday is especially for @krabberod.bsky.social. A taxopodida from the Caribbean Sea. With its long, wide oars it looks pretty different from the species I encounter in Maine! #protistsonsky #marinelife

The tiny heterotrophic cryptophyte palpitomonas with its small cell body, relatively large nucleus (shown with a green nuclear stain) and its strangely extra long pair of flagella. #protistaday #protistsonsky

Inspired by @evocellbio.bsky.social, I think I found our gal: Conchoceras caudatum! Drawing from the Challenger expedition in the mid 1870's. Happy to share this again with the additional context. What an incredible cell. #protistaday #protistsonsky #marinelife

Today a radiolarian #protistaday from the Caribbean. It is a privilege to have the means, support, and interest to Research the curious cell biology of radiolarians. I have many like this to share and will hopefully have opportunities to dive into their cell bio in the future. 🦑 #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
