There are hundreds of sea louse species, each one more disgusting and vile than the last. Perhaps the worst is the nameless one that has no interest in killing fish, but rather each other. It all starts when a male gets horny. Try to stop fantasizing over lice boners, though, because they're rough lovers, and not in a good way. A male of this species grabs just about every female he can find (up to 25 at a time), drags them back to what I'll generously describe as a dungeon, and has his way with them. There's no mating dance, no cuddling, no intense conversation into the night -- just a whole bunch of, let's face it, louse rape.
And f**k those poor girls' dreams of escape: Scores of babies weigh them down almost immediately. These are live births, too, so the mom-to-be can't just poop out a bunch of eggs and retreat to the nearest single ladies' club. In fact, they won't be skipping town ever again, because once the kiddos are ready to be born, this happens:
Yep, after bouncing around inside their mother like she's an old-timey rubber room, baby lice escape her warm confines by literally chewing their way out. Then they just waltz out of her gaping maw, replacing the primal screams she no doubt wanted to emit but tragically could not. Wow, even human children usually aren't capable of such bullshit. f**k Alien and its bush-league chestbursters -- how nobody's made any B-horror schlock about killer louse sperm is beyond me.
