Photon hunting in the twilight zone: Visual features of bioluminescent sharks

Wednesday, August 6, 2014 - 13:01 in Biology & Nature

The eyes of deep-sea bioluminescent sharks have a higher rod density when compared to non-bioluminescent sharks, according to a study published August 6, 2014 in the open-access journal PLOS ONE by Julien M.
