Anglerfishes of the suborder Ceratioidea employ an unusual mating method. ...
At birth, male ceratioids are already equipped with extremely well developed olfactory organs that detect scents in the water. When he is mature, the male's digestive system degenerates, making him incapable of feeding independently, which necessitates his quickly finding a female anglerfish or else dying. The sensitive olfactory organs help the male to detect the pheromones that signal the proximity of a female anglerfish. When he finds a female, he bites into her skin, and releases an enzyme that digests the skin of his mouth and her body, fusing the pair down to the blood-vessel level. The male then atrophies into nothing more than a pair of gonads, which release sperm in response to hormones in the female's bloodstream indicating egg release. This extreme sexual dimorphism ensures that, when the female is ready to spawn, she has a mate immediately available.[2]
