    @Cristina: Great post. I am assuming this is a polychete worm. One place to start would be is to look at my old post on the same; but from a marine environment.


    I also took some high speed videos of these hairs that shoot in and out incredibly fast.

    Also; from your video – I can tell – you lens got a little drop of water. Just take a tissue and wipe it off; and let it dry. You will see the blurr go away 🙂

    Fantastic post. Can you also share the pond you collected this beast from.

    Keep exploring..

    Hi, Manu. Don’t you think it is an oligochaeta as it exhibits few setae and has no parapodia? Thanks for your words. I’ll clean the lens very carefully: my foldscope is pure treasure and have only that lens. Each time I use it I literallly dive in ecosystems, biological structures, .. and feel we really know so little just using our naked eyes. Could there exist any living creature capable of seeing the macroscopic and the microscopic? Don’t know if it is a naive question.

    @Cristina: What an interesting question you ask “Could there exist any living creature capable of seeing the macroscopic and the microscopic?” – I don’t know; but that is indeed a very interesting question.

    Taking literally, we should think about seeing “optically – with light” – just in that I can imagine many possibilities, including does any creature have a dynamic optical zoom. I don’t know – but I would love to find out. What’s fascinating about your question is that it is technically feasible; the microscopic readout can be used as a sensor to figure out the state of the microscopic environment while the macroscopic imaging gives you state of your immediate environment/surrounding.

    The first place to start would be is to make a single plot of magnification with body size? We need to only include animals that truly form an image of the surrounding. Knowing just that is incredibly hard actually..

    Fascinating question.. Let’s think more about this collectively.

    @Laks: Got any ideas?

    Really nice video @cristina
    @manu, if I’m not mistaken I think some species of bird do have optical zoom.
