🔬 物种简介
光颌鱼能发出深海中极为罕见的红色生物光——而大多数深海生物无法感知红色光，因此这相当于一盏"隐形探照灯"，只有光颌鱼自己能看到。其颌骨没有底部皮肤，如骨架一般张开，可吞下比自身大得多的猎物。
Wikipedia
The stoplight loosejaws are small, deep-sea dragonfishes of the genus Malacosteus, classified either within the subfamily Malacosteinae of the family Stomiidae, or in the separate family Malacosteidae. They are found worldwide, outside of the Arctic and Subantarctic, in the mesopelagic and bathypelagic zones, below a depth of 500 meters. This genus once contained three nominal species: M. niger, M. choristodactylus, and M. danae, with the validity of the latter two species being challenged by different authors at various times. In 2007, Kenaley examined over 450 stoplight loosejaw specimens and revised the genus to contain two species, M. niger and the new M. australis.
