Anglerfish, the amazing sexual parasites of the abyss (EL PAÍS in English)

The study of this unique fish, whose males are born to become mere reproductive appendages of the females, could help save lives.

However, this is only the case for a few kinds of anglerfish within the wide variety that exists: among 168 species, only in 23 are the males forced to permanently join the females in order to survive. At that point, it can only survive thanks to the nutrients provided by the female, and thus it is considered a parasite. The possibility that these fish have developed an entirely new type of immune system has not been ruled out, although something akin to a reorganization of the defenses – so that they attack pathogens, but not other individuals of their own kind – is more likely to be the answer. It is only after the union that male and female become sexually mature. The male secretes an enzyme that digests both his own skin and that of the female, so that their tissues and blood vessels are forever connected. Still, finding each other in the dark of the abyss is not easy, so when they do, the males give the females an eternal kiss. In May 1917, a very peculiar fish that appeared in the nets of a fishing boat was taken to Saemudsson for study. That bioluminescence is the However, upon dissecting it, he realized that those small fish were not hatchlings – they were males of the same species. He wrote: “[The male fish is] merely an appendage of the female, and entirely dependent on her for nutrition. It was a female anglerfish of the Ceratias holboelli species. Under its gills, Regan noticed a fish that was attached in much the same way as Saemudsson had previously described.
