@mbari_news: That moment when you spot a deep-sea cutie 😍⁠ ⁠ Deep-sea hatchetfishes in the family Sternoptychidae cleverly camouflage themselves in the dark depths of the ocean—they have light-producing organs in rows along their bellies. Known as counterillumination, this adaptation allows the fish to match the daylight filtering from surface waters above and effectively hides the animal from predators that may be lurking below. Each species has a unique pattern of lights, and individuals can adapt their lights to whatever color is filtering down from the light above. ⁠ ⁠ These minuscule midwater fishes (about the size of a quarter) use their tubular eyes to search for prey in the water column. While their eyes can focus near or far, they are specifically pointed upward to scan for tiny crustaceans and zooplankton in the waters above. Their mouths are pointed in the same direction, making it easy to grab their next meal once it's been spotted. #MBARI #DeepSea #DeepOcean #abyssalcutie
