The male anglerfish are notably smaller than the females, and they do not use the same bait females do to hunt. The Male Fish Are Parasites The male anglerfish are notably smaller than the females, and they do not use the same bait females do to hunt. The exact way how the anglerfish finds these bacteria is still unknown. These bacteria can only survive in seawater, and the deep-sea habitat of the anglerfish is most suited for their survival. They cannot synthesize the chemicals necessary for this luminescence by themselves. The reason for this is because this bacteria is usually unable to create the luminescence if it is not connected to the anglerfish. This tip is called the esca, and it is believed the bacteria and the anglerfish have developed a symbiotic relationship. We have previously noted that the source of this light is the bacteria that dwell around the fleshy tip used as bait. Let’s talk more about the light the anglerfish use to hunt for prey, because it is interesting, to say the least. They Have Symbiotic Relationship With Bacteria They cannot synthesize the chemicals necessary for this luminescence by themselves. They are also known to swim sometimes inverted, with their “angler” hanging downwards, which is a method of enticing their prey. Once they do decide to swim, they can reach speeds of up to 0.24 body lengths per second, which is considered to be notably fast. This is possible because the environments they live in are quite harsh, so they need to conserve energy due to the lack of food. The anglerfish can be extremely fast swimmers when they feel like they are in danger however, they are known to passively drift most of the time. They Can Swim Fast If They Want To The anglerfish can be extremely fast swimmers when they feel like they are in danger. Using this ability, it can swallow prey that is twice as large as the body of the anglerfish itself. The anglerfish also have thin and flexible bones, which allows it to extend its jaw and stomach to enormous sizes. The second purpose is to prevent the food from escaping its mouth. The first one is that they cannot create any resistance to the food that is gliding towards the stomach of the anglerfish. The teeth of an anglerfish can be depressed, which serves two equally scary purposes. Both jaws are lined with inwardly inclined small teeth. Their mouth is so wide it extends all over the entire circumference of their head. When we say that the anglerfish have a big mouth, we mean that literally. They Have A Big Mouth Certain subspecies of the anglerfish are starting to be recognized by Greenpeace, and added to their red list. However, given its current situation, the anglerfish might become endangered very soon. The meat of the anglerfish is consumed in several parts of the world, most notably in Korea and Japan. This means that they are commonly sold for consumption, but are most likely sourced from unsustainable fisheries. Certain subspecies of the anglerfish are starting to be recognized by Greenpeace, and added to their red list. They Are Close To Being Endangered Certain subspecies of the anglerfish are starting to be recognized by Greenpeace, and added to their red list.ĭuring El Niño phases, groups of anglerfish can rise to the surface, which can sometimes result in large groups of them being found floating dead. The anglerfish has plenty of exciting things about it, and we will delve deeper into several of them in this article. However, despite popular belief, some swim closer to the surface, so do not be frightened by its looks if you run into one while swimming. These fish can be found all over the world, most of the time dwelling near the seafloor. The fleshy growth that comes out of its head has the function of a lure that the anglerfish uses to catch other fish. The anglerfish is a bony fish that got its name because of its specific method of predation. However, if you are still here, we are going to talk about what many consider to be the ugliest animal on Earth. One look at an anglerfish, and you want to forget all about it, let alone learn seven interesting facts about it.
