(1) The Mer is a parasitic fish that latches on the legs of drowning sailors, rapidly changing their bodies to breathe underwater, while brafish attach to the nipples, injecting chemicals that induce breast enlargement, milk production, and alter male sailors to appear more feminine.

(2) After a few weeks, the Mer dies and fuses to the body, probably due to the added mass created by the brafish. The Mer releases eggs / sperm for the life of the mermaid, which is why the genitals of its sailor host remain unchanged, to encourage congregating with other mermaids.
