There’s no need for the pinecone fish to blindly rummage around for food in the dark, thanks to a special adaptation. Fish in the family Monocentridae — which are typically found in the Indo-Pacific — have two organs located on the lower side of their jaw that are colonized by luminescent bacteria.

The result? Mother Nature’s very own version of headlights. This adaptation helps the little fish — which can reach 8 inches in length — attract zooplankton and shrimp at night. The headlights appear orange in daylight and a green-blue at night.
