Figure 1. The deep-sea chirostylid anomuran crab, Eumunida picta, as viewed under typical submersible lights (left panel), as corrected for the color of light in the deep sea (middle panel), and as corrected for color and also for the typical (and relatively poor) visual acuity of a deep-sea crab (right panel). Note how well the red and white coloration of the crab disrupts its outline and effectively camouflages the animal. Image courtesy of Bioluminescence Team 2009, NOAA-OER.
