  1. #NewSpecies of #fish from #Antarctica highlights its threatened ecosystem phys.org/news/2024-08-species-

    Akarotaxis gouldae, a new species of #Antarctic #dragonfish from the western Antarctic Peninsula mapress.com/zt/article/view/zo

    "a population of #dragonfishes may have become isolated within deep trenches under #glaciers, surviving on food pushed in by the moving ice. Once the glaciers retreated, this subpopulation had become distinct enough to be reproductively incompatible with Akarotaxis nudiceps"

  2. When searching for light and a mate in the deep, dark sea, male #dragonfish grow larger eyes phys.org/news/2024-07-deep-dar

    Sexually dimorphic eye size in #dragonfishes, a response to a bioluminescent signalling gap royalsocietypublishing.org/doi

    Like many creatures that inhabit the dark #DeepSea, dragonfish survive thanks to numerous adaptations, including glowing #bioluminescence. But females are not quite as bright as males... male #fish have evolved larger eyes to find females who produce less light.

  3. Not seeing much #mesopelagic #fish action here yet, so I thought I'd get the #oceantwilightzone party started here on Mastdon.

    This beautiful fish is a #dragonfish (Stomias boa), a #mesopelagic predator found across the #OTZ of deep ocean basins. Typically caught between 400-600 m depth, this immaculate specimen hitched a ride to the surface, ensnared by a single tooth, on the outer mesh of #CCGSAmundsen midwater trawl. August 2019, Labrador Sea.

    “The real stars of the show are the #fish. There are blind #eels and #TripodFish, #hatchetfish and #dragonfish, with all of these #bioluminescent organs on them and lures coming out of their heads. They’re just extraordinary.”
