    Young squids

    6903

    Real-time movie of young squids. Squids are often used as research organisms due to having the largest nervous system of any invertebrate, complex behaviors like instantaneous camouflage, and other unique traits.

    This video was taken with polychromatic polarization microscope, as described in the Scientific Reports paper “Polychromatic Polarization Microscope: Bringing Colors to a Colorless World” by Shribak. The color is generated by interaction of white polarized light with the squid’s transparent soft tissue. The tissue works as a living tunable spectral filter, and the transmission band depends on the molecular orientation. When the young squid is moving, the tissue orientation changes, and its color shifts accordingly.
    Public NoteSmall, translucent squids swimming. As they move, the translucent color of their bodies changes from shades of blue/greens to pink/purples.
    Internal NoteYes, I give my permission to add the three movies (crane fly, circular lamellipodia, and baby squids) and the mouse brain slice image to your image and video gallery.

    InvestigatorReal time movie of baby squids taken with polychromatic polarization microscope https://www.nature.com/articles/srep17340 --this reference is just to show the technique. Squids and their development are a major topic of the research at the MBL. See, for example, https://www.mbl.edu/news/squid-and-octopus-genome-studies-reveal-how-cephalopods-unique-traits-evolved The color is generated by interaction of white polarized light with the transparent soft tissue. The tissue works as a living tunable spectral filter, which transmission band depends on the molecular orientation. When the baby squid is moving then the tissue orientation changes, and its color is modified accordingly. https://figshare.com/articles/media/playing_baby_squids/9733829 Pictured are Doryteuthis pealeii, often called the “Woods Hole squid”
