The male angler fish is significantly smaller than the female. 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 slowly atrophies, losing his digestive organs, brain, heart, and eyes and ends as nothing more than a pair of gonads, which release sperm in response to hormones in the female's bloodstream. Multiple males can be incorporated into a single female

Lamprey ~Petromyzon marinus ~Lampreys (sometimes also called lamprey eels) are a family of jawless fish, whose adults are characterized by a toothed, funnel-like sucking mouth. While lampreys are well-known for those species which bore into the flesh of other fish to suck their blood, most species of lamprey are non-parasitic and never feed on other fish. In zoology, lampreys are sometimes not considered to be true fish because of their distinctive morphology and physiology. ✿
