spiders will pull their own legs clean off if they get damaged because most of them can regrow legs during molting, which explains why you often see spiders missing a leg but never any missing half a leg?
some remarkably distressing scientists proved this by getting a spider to pull off all of its legs and then feeding its limbless torso for months until it sprouted a full complement of legs again and then hopefully used them to get the fuck out of dodge
baby spiders don’t get lenses until their first molt and before that they just have baby eyes and while this ought not to be any weirder than the concept of baby teeth, welp,
there are so many spiders floating around thousands of metres up in the air that they’re described as “aerial plankton”
The Sky Is Full Of Spiders
there are spider-parasitising spiders but instead of laying eggs in organs or stealing blood or anything like that they just ride on top of bigger spiders and steal snacks when their mighty steed is eating
there are ant-mimicking spiders that use their disguises to raid ant nests and w/e but there are also ant mimics that just. hang out. they make fake ant colonies full of fake ants. sometimes the actual ants that they’re mimicking find their house and live with them. stealth 100
some mother spiders live in communal family nests, where multiple mothers can work together to bring down bigger prey while all their collected babies are cared for by the babysitters
some mother spiders feed their babies mouth to mouth like birds
some mother spiders carry their babies around and i was aware of this but not the fact that if you steal their eggsac they’ll freak out and search for it for hours and sometimes end up adopting anything that’s vaguely the right size, they will carry around empty snail shells for weeks and lovingly dote on them…
guys i am literally about to cry over spider moms
i borrowed the book op cites from the library (biology of spiders by rainer f. foelix) because of this post and my two favourite new spider facts are
-they don’t just have an exoskeleton – they also have a secret partial inside skeleton
and
-you know the guy who gave spiders drugs and took pictures of their fucked up webs? he ended up studying them because his buddy was studying garden spiders and they spin webs at 2-5 am and his buddy was like, Ugh, fuck this, i want to sleep in, do you have anything i can give these spiders to make them spin webs at not two in the morning -and this guy, A Pharmacologist, was like, hell yea, here are some amphetamines for your spiders -and all those did was make the spiders spin some exceptionally weird webs at 2-5am -and i guess his buddy gave up in disgust at these spiders who wouldn’t let him sleep but mr. spider amphetamines was like, you know what, this is cool, i’m gonna keep going with this
the fact that we can’t drink sea water even tho its the most common type of water just bc its 3% salt yet we can safely consume multiple forms of literal poison and even benefit from doing so just blows my fucking mind
Am I the only one whose internet addiction started with my parents not letting me fucking go anywhere
This but I also had no friends so I wouldn’t have anywhere to go if I was allowed
this is a thing! danah boydis a researcher who has been studying social media for over a decade and in her 2014 book it’s complicated she argues that teenage social media “addiction” (which she also contends is like…..not actually a thing) is a result of the fact that “today’s teenagers have less freedom to wander than any previous generation” because “parents argue that these restrictions are necessary in an increasingly dangerous society, even though the data suggest that contemporary youth face fewer dangers than they did twenty years ago.”
as a result, teenagers are reclaiming these lost social spaces (which their parents and grandparents had in the form of mall hangouts, drive-in theaters, after school parking lots, etc) by using social media, where they can continue to “engage in crucial aspects of maturation: self-presentation, managing social relationships, and developing an understanding of the world around them,” aka stuff that teens are Supposed to be doing
Alien: You’re telling me that in times of great distress humans have been known to suddenly gain the strength necessary to lift objects more than a dozen times their own weight?!
Human: Yeah, it’s called “hysterical strength” and it usually happens in life-or-death situations, like when someone gets stuck under a car or something and someone lifts the car to get them out. We can’t really test it though, ‘cause it only happens spontaneously.
Alien: Humans have the ability to tap into untold strength and power and you don’t even know how you do it?
Human: Pretty much, yeah. We think it has something to do with temporary analgesia, so we just don’t feel the pain we should when we pick up a 3000-pound car.
Alien: YOUR PAIN RESPONSE JUST SHUTS OFF?
Human: Yeah, it’s like an adrenaline thing? Do you not have that?
Alien: Fuck you and your entire species of tiny juggernauts.
Did this post just use a dialogue format to trick me into learning science
Had to check this out on wikipedia at least and boy was that a ride
SCIENCE!
Were puny and weak compared to most large mammals but we got several huge advantages not even counting our brains. 1) endurance. 2) incredible healing factor. 3) Hysterical Strength.
Silver does this also, which was probably handy for silverware before antibacterial dish soap was invented.
That’s mentioned in the article as well. They also stated that a copper or silver container can disinfect a pot of water in a few hours. im gonna add a copper vessel to my emergency provisions now. @yourunclejingo you may find this stuff interesting too.
Its almost like our ancestors did shit that made sense even if they didn’t always fully understand why.
Roy Mustang snaps his fingers accidentally (while wearing his gloves)
What people think will happen: fire, death, destruction
What will actually happen: a small spark
Why people are wrong: they think Roy’s Flame Alchemy actually creates flame, whereas what he’s alchemizing is the oxygen concentration of the air. Alchemy takes concentration and intelligence so he can’t accidentally move air particles around to make the air so oxygenated as to be flammable. The finger-snap just ignites the oxygen. If the air is normal, it’s not going to ignite.
Extra fun fact: you can probably tell if Roy Mustang is about to set you on fire. The air will feel intoxicatingly easy to breathe because it’s pure oxygen. During the war, Ishvalans probably learned to GTFO if they felt heady and energized.
Extra extra fun fact: Roy Mustang doesn’t need to set you on fire to kill you. He can probably just remove all the oxygen from the air around you, and you’ll suffocate.
The point of this post: flame alchemy is both really cool and really simple.
The kicker: to use flame alchemy effectively, you probably have to visualize the shape of the oxygen cloud that’s going to form. This probably requires a lot of focus.
In a simple experiment, researchers at the University of Chicago sought to find out whether a rat would release a fellow rat from an unpleasantly restrictive cage if it could. The answer was yes.
The free rat, occasionally hearing distress calls from its compatriot, learned to open the cage and did so with greater efficiency over time. It would release the other animal even if there wasn’t the payoff of a reunion with it. Astonishingly, if given access to a small hoard of chocolate chips, the free rat would usually save at least one treat for the captive — which is a lot to expect of a rat.
The researchers came to the unavoidable conclusion that what they were seeing was empathy — and apparently selfless behavior driven by that mental state.
Giant tarantulas keep tiny frogs as pets. Insects will eat the burrowing tarantulas’ eggs – so the spiders protect the frogs from predators, and in return the frogs eat the insects. Source
This has blown my mind for years. It’s so unreal. It’s almost the same exact reason humans and cats started living together.
Tiny frogs are tarantula housecats. A science fact seldom gets to sound that much like meaningless word salad.
This is legit, guys. And I’m excited about it.
Someone needs to draw a tarantula person with a tiny pet housefrog now. Please let this be a thing.
