Mobile Bay Reef Keepers

Because angler fish are so sparsely populated throughout the vast millions of cubic miles of ocean, chance mating encounters between males and females would be unlikely. In fact, when deep-sea anglers were first brought up in trawls they puzzled scientists because they were all females. Then someone noticed small "growths" on the female that turned out to be males. When a tiny male meets a female he bits into her flesh and literally fuses with her body. Like the linking together of web sites on the Internet, the two blood supplies also fuse together so that the male obtains nutrients and oxygen from the female. Without any need for most of his organ systems, such as eyes and digestive organs, the male's body degenerates into essentially a pair of sperm-producing testicles. Thus the female essentially becomes a hermaphrodite with up to six or more of these tiny male parasites attached to various parts of her body. Although functionally bisexual, the eggs and sperm come from genetically distinct parents, thus providing vital genetic variability through meiosis and genetic recombination. As a functional hermaphrodite she can have sex any time or place, without worrying about meeting a male in the dark abyss of the ocean. Clinging to her body like minute, blood-sucking parasites, the males have little interaction with the female, except to fertilize her eggs with sperm.
