Who do anglerfish live with?

How long does an anglerfish live?
Female anglerfish usually live a little longer than male ones. Females live for about 25 years whereas males live for around 21 years.
How do they reproduce?
Deep-sea anglerfish use a lure to attract mates. Females are much larger than males and they have lighted lures. Males are usually not predatory in nature, only females are. A female anglerfish is much larger and males attach their bodies to females by biting them. Sometimes they do not detach themselves and continue sharing the female's bloodstream, providing them with sperm to fertilize the eggs. In other scenarios, males detach themselves and look for other partners to mate with. They also take part in external fertilization in which females lay the eggs outside and males immediately release sperm and participate in fertilization.
What is their conservation status?
According to the IUCN Red List, anglerfish are in the Least Concern category. From 2007, they have been restrictions placed on anglerfish to try and reduce the number of anglerfish being caught. Since 2001, a special permit is required to catch anglerfish. In 2000, it was advised to reduce the fishing rate by 40%.
Anglerfish Fun Facts
What do anglerfish look like?
Anglerfish range from dark brown to dark gray. They are roundish in shape with large heads and translucent teeth. They also have an outgrowth protruding from their heads which they use to lure prey and attract mates. They have a large mouth with fang-like teeth which are slanted inwards. This helps them to efficiently grab their prey. They have a modified dorsal fin ray that is capable of illuminating itself. In certain cases, bacteria help in the luminescence. Anglerfish do have eyes however they are very small and pretty useless in their dark habitat of the bottom of the ocean. They use their other senses to move around, find prey, and attract a mate.
How cute are they?
Deep-sea anglerfish look extremely deadly and dangerous. They are carnivorous and lure in prey with their dorsal fin light. Their sharp teeth and large teeth make them extremely scary to look at.
How do they communicate?
Anglerfish communicate with each other through a lateral line system with which they sense water pressure and other vibrations. They also have open nerve endings and chemosensory cells which act like tastebuds for them.
How big is an anglerfish?
Anglerfish have varying lengths. Deep-sea anglerfish size vary from 1-7 in (2-18 cm) in length to 39 in (100 cm) in length.
How fast can an anglerfish swim?
Anglerfish aren't fast at swimming due to their large head and roundish body. The deep-sea anglerfish is known to swim at a speed of 0.24 mph (0.37 kph) of its body length per second.

Are they dangerous?
These fish are not specifically dangerous to human beings since they live in the depths of the sea where the external pressure is physically impossible for human beings to withstand. However, they are considered to be strategic hunters as they use their rod like structure to lure in prey and feed on their flesh. Their hunting tactics and ferocious nature has resulted in naming them the seadevil.
Would they make a good pet?
Anglerfish have various different species. The anglerfish belonging to the suborder Ceratioidei live in shallow water which makes it possible to keep them in aquariums. However, the species residing in the depths of the ocean can't be kept as pets since the water pressure accustomed to their body can't be managed in a tank.
Did you know...
The sole purpose of the existence of a male anglerfish is to find a female partner for reproduction. The mating takes place when male fish attach themselves to a female by biting them with their teeth and their mouth gets attached. They also share the bloodstream of females.
Most ceratioid female anglerfish have a rod-like structure called the illicium which they use to lure in prey and also attract males in order to mate.
Anglerfish belong to the teleost order which is an infraclass, named Lophiiformes.
Certain symbiotic bacteria help in the luminescence process which helps them to attract prey and attract a mate.
Anglerfish, also known as the seadevil, is one of the deadliest looking creatures on earth. They have scarred-like skin and large mouths. This flesh-eating species has a fishing rod on its head which is used to attract prey.

Anglerfish have around 210 species. They are divided into four groups namely batfish, goosefish, frogfish, and deep-sea angler. The fish belonging to the cCratiidae group have an unusual process where the highly reduced males mate by attaching their mouths to the female body, showcasing their parasitic behaviour. There are also black seadevils (Melanocetus johnsonii) which have expandable stomachs and are known as ambush predators.
