"There are about 60 different Glass Squid species and all have a very unique appearance. These cool looking animals can be found in the middle depths of the ocean where the sun-lit water combined with their transparency makes a pretty good camouflage. To make this camouflage even better some species actually have a bio-luminescent light organ on the undersides of their eyes. How does this help with camouflage you ask? Well, the light it emits will cancel out their shadow, so now you have a transparent animal swimming through the water without a shadow. You won’t know it is there until you swim into it".
