      @Blackmark52 3 года назад +24

      "An organic Roomba"
      But what struck me in this video that the perception of these organisms as flat like a roomba is wrong. We tend to see the very short focus of microscopes as showing flat objects, but if you watch, the D is constantly rotating. It is much more like a very short, very fat torpedo than a like a roomba. And the idea of bouncing around the room is too simple as well. The critter is spiralling through three-dimensional space. Awsome.

My own guess as a non-expert is, that they can detect chemical signals from other organisms, maybe their surface proteins or trails of chemicals they leave behind and when those signals read "non edible" the microbes back off.

    This is beautiful. Like a bloodsucking mole. Watching the microcosm reminds me o watching a finished machine learning A.I that has completed forming its strategy for completing a specific goal. The Didiniums goal is to effectively move and suck the insides of Parameciums. I wonder if over enough microcosmic evolutionary time and generations, Parameciums can come up with a survival strategy to avoid Didiniums.

      It depends on the genus. It's usually a protein delivered into the interior cytoplasm by a flexible, extending organelle called an extrusome. The toxin interferes with cellular metabolism, either temporarily or permanently. There will probably be a future episode on this topic, as it is a common form of both protection and predation, and comes in five different structures.

    So Didinium can sometimes be like Monty Python's 'Mr Creosote'...... "Just one, small, tiny wafer thin mint???" Hahahaha 🤣🤣🤣🤣

    I'd like to know what happens to the prey (e.g. paramecium) inside the didinium. How does it digest it? The internal structure of a unicellular organism is a mystery to me.

    Are those bubble/droplet looking things inside these cells the organelles?

    It's like an intelligent HEAT round that fires off a load of paralyzing agent instead of a jet of molten copper which, thereafter, sucks the stew of the crew out including the entirety of the tank.
