Jocelyn Malamy and Elizabeth Lee of University of Chicago have been working with MBL's Michael Shribak to apply a new technique for imaging jellyfish and other transparent marine and fresh water animals. In the video below, the iridescent colors depict the birefringent layers in squid skin. This video was captured with the polychromatic polarization microscope, which was invented at the MBL.

Here are plankton (copepods) darting about, also captured at MBL with the polychromatic polarization microscope: https://figshare.com/articles/Plankton_under_polychromatic_polarization_microscope/9752837
