The mantis shrimp Lysiosquillinglabriuscula

June 8, 2010
The mantis shrimp Lysiosquillinglabriuscula, as seen in white light (left) and fluorescing under blue-light excitation, as viewed through a filter that blocks the blue exciting light (right). Note the strong yellow fluorescence from patches on the antennal scales (the flaps that project laterally below the eyes) and on the carapace, which duplicate the yellow reflectance seen in white light. By fluorescing yellow in natural blue illumination at greater depths, this species of stomatopod crustacean can maintain a relatively constant yellow signaling color even in the absence of yellow illumination.
