When we hear the name Anglerfish what immediately comes to mind for most? The image that appears may look something like this, however, this would also be accurate. This is because fish are commonly known as angler fish.
Sea devil belongs to the order Lophiiformes which is split up into five different supporters containing more than 300 individual species. These 5 suborders contain the fish typically referred to as monkfish, frogfish, sea toads, batfish, and sea devils. Technically speaking any fish from any of these suborders could be referred to as an anglerfish. So, for the sake of clarity, we’ll be focusing on sea Devils or deep-sea anglerfish.
Any instance of the word anglerfish in this article from this point forward will be in regard to these fish anyway on to those freaky fishes. Sea Devils are deep sea-dwelling fish who typically live somewhere between half a mile and one and a half miles below the ocean’s surface. Though some live more than two miles down since they live in an area that’s so difficult for us to explore. We have limited information on them but some of the facts that we do know are pretty impressive.
There are more than 150 species of deep-sea anglerfish and probably more to be discovered many species possess a bioluminescent organ that developed on the 1st spine of their dorsal fin or the fin along their back as a lure for drawing in prey, this is called an Eska. The light of this lure is created via a symbiotic relationship between photo bacterium and female angler fish yes only female deep-sea devil had this lure. The males will we’ll get to them in a minute it’s also been documented that some species of deep-sea anglerfish are able to produce their own bioluminescence making them the only group of animals discovered.
So far according to the American Museum of Natural History to use glowing bacteria and produce their own light by this logic we can surmise that the angler fish seen in fine Nimmo is likely a female left vent anglerfish. Since she lights up even more upon discovering merlin and dory but that’s just a theory in a study of monkfish. It was discovered that they seemed favored dining on crustaceans and other fish perhaps deep-sea anglers seek out similar meals as well sea devils may also consume squids as suggested by NatGeo wild.
Sea devil adaptations
Weird killer of the deep whatever they eat it’s likely it’s only the females doing most of the munching what male sea devils lack in the eschaton. They make up for in the size of their nose it’s assumed that this adaptation has occurred due to the single life purpose of the male deep-sea devil to find a mate. The deep parts of the ocean are a dark and mysterious place, the kind of place that will make you want to hold tight to your significance.
When a male sea devil meets up with a female he will latch on to her with a big bite at her belly and over time become fused to her body becoming solely dependent on her it’s not uncommon for a female deep-sea anglerfish to have five or more males attached to her at any given time. All of this ensures the survival of their species with the males taking codependency to a whole new level.
This gives females open access to sperm at any time she is ready to produce offspring deep-sea anglerfish are typically less than a foot in length with males appearing smaller than females. They are usually dark brown or grey in color and can often appear black as well one of their defining characteristics is that they lack a pelvic fin. After very early stages of life, they’re considered to be the most species-rich group of animals found in the deep ocean and more species are being found at a steady rate as recently as 2015 a new species of Anglerfish or sea devil was found in the Gulf of Mexico
