![]() For example, the angler fish developed such a freakishly large jaw and a distensible stomach because the fish needs to take advantage of every prey opportunity available because food is scarce so far below sea level, according to The New York Times.Īccording to the Monterey Bay Aquarium Research Institute (MBARI), "fewer than half a dozen have ever been captured on film or video by deep diving research vehicles." In November 2014, MBARI caught incredible footage of a Black Seadevil Angler and shared that it was the "first video footage ever made of this species" at the depth of 600 meters.Īnglerfish research opportunities have been limited, but as tech develops to reach deeper into the abysses of the sea, we'll likely discover more about the enigmatic species and all the other strange creatures that lie in the deepest parts of our oceans. It's also because of this extreme environment, where everything is dark and atmospheric pressure is high, that species like the angler fish developed such strange evolutionary features uncommon in other species. More than a fish, an anglerfish might resemble a prehistoric animal found in the oceans deepest parts. Abnormal Living ConditionsĪnglerfish are also weird because we know disconcertingly little about them and the habitat in which they live. This is a survival adaptation especially since food is so scarce this deep in the ocean. ![]() Additionally, Angler teeth curve inwardly in order to prevent prey from escaping. Female anglerfish of the species Photocorynus spiniceps, 46 mm, with a 6.2 mm parasitic male fused to her back. After the prey are draw near enough by its light. It uses the bioluminescence to lure its food, mostly smaller fish. The Anglerfish is a territorial deep-sea fish that, like any other abyssopelagic animal, has the ability of bioluminescence, which is a common characteristic among deep-sea creatures. By the time the prey realizes the lure isn't something they themselves can eat, they've become the Angler's meal.Īngler's also have a distinctive wide mouth making it easy for the fish to munch on prey of various sizes. The Anglerfish is a minor antagonist in the 2003 Disney/Pixar animated film, Finding Nemo. The lure emits a glow, produced by bacteria living within, that attracts prey. On top of this weirdly alien mating behavior, anglerfish also have a bioluminescent lure protruding from their heads. Female anglers may carry six or more males on their bodies at a time according to National Geographic. Females eventually absorb the males who lose organs, such as their eyes during the process, until the male becomes a sac with sperm which the female uses at her leisure to procreate. In Japan, anglerfish is considered a delicacy and can fetch a premium price.In March 2018, footage was captured that showed a pair of mating anglerfish floating in the deep, performing perhaps the strangest mating ritual on the planet.Īnglers engage in parasitic mating where male anglers, which are typically much smaller than the females, become permanently fused together. They are compared to lobster in taste and texture. Many species of anglerfish are fished commercially throughout the world. At this depth, there is almost no light and the water is near freezing. ![]() The deep sea angler is found throughout the world's oceans at depths of over 3,000 feet (914 meters). As they mature, they return to the depths below. Once hatched, the larvae swim to the surface and feed on plankton. This thin sheet of eggs floats free in the sea until the eggs hatch into tiny larvae. The female will lay her eggs in a thin sheet of gelatinous material two or three feet (about one meter) wide and about 30 feet (9 meters) long. This bizarre method of reproduction helps to ensure that when the female is ready to spawn, she has a mate instantly available. A female can carry up to six males on her body at a time. The male will spend the rest of its life joined to the female like a parasite, getting all of his nourishment from her body. The two become fused together and their blood vessels join as one. Once he bites into her skin, he releases an enzyme that dissolves the skin of his mouth and that of her body. The male angler has small hook teeth, which it uses to attach itself to the female. It must now find a female or die of starvation. ![]() When a male angler matures, its digestive system degenerates, making it impossible for it to feed on its own. It is about the size of a small finger and black in color. The male angler is much smaller than the female and completely different in appearance. The deep sea anglerfish has an extremely unusual method of reproduction. Deep sea anglerfish species Bufoceratias shaoi
