    C. elegans trapped by carnivorous fungus

    6963

    Real-time footage of Caenorhabditis elegans, a tiny roundworm, trapped by a carnivorous fungus, Arthrobotrys dactyloides. This fungus makes ring traps in response to the presence of C. elegans. When a worm enters a ring, the trap rapidly constricts so that the worm cannot move away, and the fungus then consumes the worm. The size of the imaged area is 0.7mm x 0.9mm.

    This video was obtained with a polychromatic polarizing microscope (PPM) in white light that shows the polychromatic birefringent image with hue corresponding to the slow axis orientation. More information about PPM can be found in the Scientific Reports paper “Polychromatic Polarization Microscope: Bringing Colors to a Colorless World” by Shribak.
    Public NoteA worm wiggling as it attempts to move forward while its tail is snared by fungal ring traps. More ring traps can be seen in the background attached to crisscrossing fungal threads.

    Hi Rachel,

    I am wondering if you would be interesting to add to your gallery the attached image of C. elegans. The photo was captured with quantitative orientation-independent differential interference contrast. The scale bar is 100 µm.

    You can also consider adding a video of trapped C. elegans worm https://figshare.com/articles/media/Caenorhabditis_elegans/15046812

    Thank you for your consideration, Michael

    InvestigatorReal-time movie of a carnivorous fungus A. dactyloides that traps and eats nematodes. This fungus makes many circular ring traps in response to the presence of C. elegans worms. When the worm enters the ring, the ring rapidly constricts to trap the worm so that it cannot move away. The fungus will then send in hyphae that will kill and eat the worm from the inside. The size of imaged area is 0.7mm x 0.9mm.

    The movie was obtained with a polychromatic polarizing microscope (PPM) in white light that shows the polychromatic birefringent image with hue corresponding to the slow axis orientation. More information about the microscopy that produced this image can be found in the Scientific Reports paper “Polychromatic Polarization Microscope: Bringing Colors to a Colorless World”. PPM was invented at the MBL and has been developed with support of NIGMS grant R01 GM101701.
