Inkredible! 🦑 Real-time movie of young squids, which 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. 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.
