So far I've found 2 tardigrades, 3 rotifers and a bunch of little guys I'm not sure what are, but they were in a clump of moss on the roof of my garage! Not sure how they got up there but I'm happy I looked! Also got a sample from a local pond that I'm finding tons of little critters in! Can't wait to see what else I can find!

Primo, when you watch a nature show about tigers, do you expect a discussion of tiger bladders, see a cross-section of a tiger heart or brain, or the chemical composition of tiger mucus? Or do you expect to see a tiger in its habitat and hear a narrator waxing poetic about tiger movement? If someone says, "Journey to the Macrocosmos" or "Journey to Madagascar", do you get the sense that biology is what it's about? It's called "Journey to the Microcosmos", not "Journey Through Biology". They are just showing us the wonders in the microcosm.

This really brings me back to Gr. 11 biology when we covered the major phyla and each evolutionary advancement in each. It was amazing to see the complexity ramp up in each new phylum we covered, though each leap was enormous. Sponges to jellyfish to worms etc on to chordates. Our spiny phylum 🙃

@rotifer 3 года назад

*I remember when I was but a teenage larva in Planktonic High, my Gastrotrich buddy and I were part of the high school band. Later on we branched off and made a band of our own to impress the nematode babes at our school. We called ourselves the **_Mictic Sticks._** Quite the naughty name, I know, but let's just say that we were swimming in roundworm with each performance.*

A scientist once said that if all the matter on Earth was removed with the exception of the nematodes, we would be able to see the outlines of mountains, valleys, seas, rivers and other natural features formed by the masses of nematodes. Forests and cities would be dimly recognizable by the presence of specific kinds of nematodes, and we could even locate plants, animals and even ourselves based on the parasitic nematodes that infest each species.

@stargrazing 6 месяцев назад

Good thing to keep in mind though is that flatworms are secondarily acoelomate, they’re traditionally thought of as the “basic” branch of the animals leading up to more complex stuff but they’re really nested pretty close there with “complex” other spiralians like mollusks and annelids. They had a coelom once but got rid of it cuz they’re too cool for it 😎

I know this isn't very specific, but they look like a type of euglenoid. Without more close-up or focused images it is hard for me to say for certain or with more granularity. I'm no expert on the subject, but I've looked at enough lake water and pond water under the microscope to at least call that an educated guess. Anyone who has a better idea or more experience with them, feel free to respond with it!
