did you know that the well-known factoid that male anglerfishes degenerate after attachment until they’re basically just a pair of testes is false? i knew of course that they don’t just become “growths” on the female because I’ve handled dozens of attached pairs and every male I’ve ever seen has been very much obviously a whole and complete second fish, but I sort of assumed there was internal degeneration, perhaps muscle atrophy, etc. i can’t believe no one ever corrected me on this but this just doesn’t happen. in obligatorily parasitic species, the male actually continues to grow and increases considerably in size after he attaches to the female, because the two of them can only reach sexual maturity together. me, an octavia butler fan: is this the height of romance??
what is true is that attached males do have hugely enlarged testes proportionate to the rest of their bodies & organs, and that they receive all nutrition from the female’s bloodstream so their stomachs are always empty, though their own gills seem to still be functional, as are their fins and muscles—you can even induce movement and swimming motions on recently dead attached males. I can only assume that at some point someone said that basically the only biological function a male anglerfish needs to perform is sperm production and this got taken out of context and luridly exaggerated over time. he’s not just a pair of testicles! he’s her forever partner! one flesh one end!
there’s a type of creature that lives six miles underwater in the sunless void and it’s hatched in two bodies and unless they find each other and fuse into a single chimaeric whole they can never grow up properly. hello? hello??
That's extremely cool! also, distracted and enraptured by the writing style at the second link.
