The main reason why this fish is called a "rake-eared" fish is because the male anglerfish depends on the female to survive. I don't know if you've noticed, but female anglerfish have very strange lumps on both sides of their body. Researchers have found that these lumps are the remains of male anglerfish parasitized on females after their death.
Maybe you're wondering, "Male anglerfish parasitizing female anglerfish? What is this? It turns out that male anglerfish are relatively small, only one-fiftieth the size of females and just over 6 millimeters long, making them one of the smallest known vertebrates. To survive, the male monkfish must find a female and parasitize her body. When a male anglerfish encounters a female, it bites her and releases an enzyme to dissolve the skin tissue, thus bonding itself to her. It is at this point that the male fish begins a life of parasitism for good.
But the male anglerfish is also very sad, although it can be parasitic on the body of the female without effort, but when the male and the female combined the moment, the male's semen into the body of the female, and wait until the development of maturity, the male will soon go to the death, leaving a ball of testicles, ready for the female to ovulate when the egg fertilization. That is why the female fish has the remains of the male fish on her body.
But for the males that don't find a female, they change sex themselves and become females, thus waiting for the males to arrive. This is supposedly with the evolution of the species for them to change like this! Needless to say, these fish lead a very sad life for the continuation of their race. Do you think the male anglerfish is an "earwig" fish? The anecdote gentleman think they are full of "rake ears" fish, but also very sympathetic to these fish, after all, nature is very cruel, in order to continue the species, we must make the appropriate response!
