What exactly is a Dragonfish? Well… any number of different species/types of fish actually — from a strange bioluminescent deep sea fish (Black Dragonfish),,,,,,,,,,,to a weird sea dragon looking thing that pair-bonds for life (sea moths), to an eel looking fish that you can actually raise on land so long as you keep them moist (Senegal Bichir),,,,,,,to a freshwater fish species that looks, in many ways, unchanged from how it looked during the times of the dinosaurs (Arowana),,,,,,.
While the focus of this article will be on the (perhaps) most recognizable of these fish — the deep sea Black Dragonfish — an overview of the other “Dragonfish” fish species will be given as well. Enjoy'''
The BLACK DRAGONFISH
The Black Dragonfish (Idiacanthus atlanticus) is a species of barbeled dragonfish classified as being in the family Stomiidae. It’s found all over the world (circumglobally) in temperate or subtropical waters -typically between the latitudes of 25°S and 60°S. As mentioned before it lives quite deep - and can be found as far down as 6600 feet below the surface of the ocean.....
Black Dragonfish grow, on average, to be up to a foot and a half long — but, as with some other deep sea fish, the females are notably bigger than the males.
Black dragonfish are bioluminescent, which in deep sea fish certainly isn’t that rare, but… In contrast to practically any other species out there, the black Dragonfish produces light that straddles the border of the infrared part of electromagnetic spectrum...
As a result, with just the naked eye people don’t see much of the light produced by the black Dragonfish — just a very limited portion of the spectrum being produced by the fish.
In common with humans, most fish can’t see in this part of the spectrum either, but the black Dragonfish can. Giving it a light to hunt by that’s invisible to most others — perfect for the deep, dark depths of the oceans where it lives.
