Their array of 16 types of photoreceptors provides complex color reception, as well as linear and circular polarization sensitivity. The least-understood components of their retina are the UV receptors, of which there are up to six distinct, narrowly tuned spectral types . Here we show that in the stomatopod species Neogonodactylus oerstedii, this set of receptors is based on only two visual pigments. Surprisingly, five of the six UV receptor types contain the same visual pigment. The various UV receptors are spectrally tuned by a novel set of four short- and long-pass UV-specific optical filters in the overlying crystalline cones. These filters are composed of various mycosporine-like amino acid (MAA) pigments. Commonly referred to as “nature’s sunscreens,” MAAs are usually employed for UV photoprotection , but mantis shrimp uniquely incorporate them into powerful spectral tuning filters, extending and diversifying their preeminently elaborate photoreceptive arsenal.7 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
