Bless your heart. You got triggered.
That's okay, my guy. I can see how disorienting it is for you guys once you stick your heads outside the manosphere rabbit hole hell dimension. Take a deep breath and relax. We'll do our best to get your sorted out.
The nutrients aren't for the female widow spider or mantis. They're for the eggs. Kind of like how female mosquitos suck blood for their eggs rather than for themselves. Widow spiders and mantises don't decapitate and eat the male every time. It depends on their overall nutrition and whether or not they've been able to get the nutrients they require to lay the eggs and for the eggs to develop properly. The fact that you can intervene and she be fine doesn't mean the eggs will be fine. Also, you gonna track down and intervene for every widow spider and mantis in the world? Is that what you're suggesting? Your comment makes no sense. Spiders and bugs do not have a self awareness or consciousness, so yes, they're going to do what they are biologically and evolutionarily programmed to do. They don't know to wait for a human to come along and save them from themselves nor are they able to make a conscious choice about how they mate.
Which brings us back to the validity of her statement that they're not doing it for sport.
Perhaps it's the word 'sport' that's got you all flustered. No worries, let's consult a dictionary. I've got one right here:
Sport: an activity involving physical exertion and skill in which an individual or team compete against another or others for entertainment.
Well, there's a couple of key words here we need to pay attention to. One is competes; if the male is making a sacrifice of his head in order to reproduce, there's no competition. Willing sacrifice does not equal competition. The other word is entertainment. Outside of the occasional voyeuristic human and their cameras, there's no audience. The bugs and spiders do not appear to be observably entertained either. Just because little human boys tend to get their jollies ripping off the wings of butterflies, setting ant hills on fire, and throwing bird eggs at bird parents, it doesn't follow that mantises and widow spiders enjoy their copulation ritual, whether they're the one beheading a mate or the mate getting beheaded.
So using some basic common sense, basic knowledge of biology, and a dictionary we can easily see that female widow spiders and mantises do NOT behead their mates for sport. Sorry, you're just going to have to fulfill that fantasy elsewhere. Sanni's statement stands.
Moving on to anacondas. I don't know how to break it to you, but there are some species that will eat anything that moves and fits in it's mouth. Alligators and crocodiles are another example of this. They routinely eat smaller individuals of their own species or smaller species of the same Genus or Family. But there's no targeting specifically of males by Females or targeting of females by males. Females, who become extremely territorial during nesting/reproduction will eat an intruding female as readily as a male. Or just because she's peckish and can. So will a male. Once again, we find there's no variable of doing it for sport.
Moving on to Octopi. They're interesting, aren't they? Octopi are aggressively territorial and we're just beginning to understand them more fully. We do know that they box each other and will even attempt to box divers observing them. They also throw things. And there have been observations of them eating each other. We don't really know why, or what's driving it. Of note, boxing and hurling matches, which could arguably be considered sport, are not generally fatal, nor are they part of mating, some kind of octopus rut season, or dominance displays of some kind. You don't even see it between males and females exclusively; they just don't like each other and prefer a solitary life for the most part. Ergo, if a female eats a male, we can't say with a straight face that it's because they get a kick out of making sport of poor hapless male octopi and expect to be taken seriously. It just doesn't match up to what we've observed more broadly in the wild with any degree of certainty.
May I suggest that if you're interested in all these creatures you read a book, invest in a scholarly journal that publishes animal studies, or take a college class in zoology or something. Anything except getting your misinformation from social media; it's fucking embarrassing for you, dude. And look how wound up you get! Over nothing.
Now allthe other guys are going to see how insecure you are and peck you because you've made yourself a target for their dominance displays. All the gals are gonna see your insecurity too and avoid you because you're flash advertising that you're a lot of work and not very pleasant to be around. ::shrugs::
