Stentors: Single-Celled Giants

  • 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!

    Whoops! We said that tardigrades have six legs, but they definitely have eight!

      Well, saying they have six legs is technically correct. Just like me saying "I have one eye". If I have two, then I also have one.

    what if the relative sensation of pain to them is simply a polar function. The charge of the insulting body vs the Rotifer's. The disrcharge via contact, vs repulsion by like charges when in very close proximity.

    Definitely turquoise rather than blue.

    So what I'm hearing is my ancestor species of 3 billion years ago could look much like this? If they encode DNA in a similar way? I mean we must trace back to a single cell organism since that's all there was back then.

    How do you know the colour of the pigment if you have to use a contrasting dye to look at them under a microscope?

    3:53 How long do these rotifers live? Because a 25 minute battle could have been it's entire life span for all we know. Did it stop trying to fight, or did it just simply get old?

    Those pretty stentors' color is viridian. See Wikipedia, "Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed more of green than blue. Specifically, it is a dark shade of spring green, so it is the color between green and teal on the color wheel, or, in paint, a tertiary blue-green color. Viridian takes its name from the Latin viridis, meaning 'green'."
