This deep-sea galatheid crab is highly visible under the full-spectrum submersible lights. At blue-green wavelengths, however, it is well camouflaged. At red wavelengths it is again quite conspicuous, because the disruptive coloration on the legs is no longer effective. Image courtesy of Harbor Branch Oceanographic Institution.
