The anglerfish are one of the strangest and mysterious creatures on earth. They live hundreds of meters below sea level, and we have very few specimens of these weird sea animals. The females of anglerfish have a lure that use to attract prey. The lure was filled with bacteria that make their own light. These bizarre creatures have the most unusual mating method known as parasitic reproduction.
That means during the mating, the tiny male is attached to the female. Besides that, the male also biting into female skin and releasing an enzyme that fuses the two of them together. After the fusion, the male is completely dependent on the female, and the female provides nutrients in exchange for its sperm. They live and remain reproductive functional as long as the female lives, and can take part in multiple spawning.
