Pulse Munitions In The Morning

While researching for upcoming fish facts I ended up going down a rabbit hole on parrotfish teeth, and I need to share this information in another form than just a fish fact. This stuff is unbelievable. You know the beak of the parrotfish, right? It's formed from the fused teeth of the parrotfish, as an adaptation to have ample biting surface to scrape off and chew on coral, their main food source.

A close-up of the beak of a parrotfish. It has this honeycomb pattern which I find very cool.

Well. To constantly chew on coral, they must have some pretty hard teeth, right? And they indeed do: the teeth of the parrotfish are made up of a mineral called fluorapatite, which forms intricate, chainmail-like woven structures on a microscopic level. Fluorapatite just so happens to be the second hardest biomineral found. This stuff, the parrotfish's teeth?? They are stronger than copper, silver and gold. That's crazy, right!!?? A square inch of the parrotfish's teeth can withstand a whopping 530 TONS OF PRESSURE!! That's the weight of 88 ELEPHANTS on top of a single square inch!!!! The only biomineral that is tougher is the teeth of chitons, that is the single tougher thing in the whole world!!! Not only that, but the stiffness and hardness of the teeth increases the more we get closer to the tip (as the mineral fibers get closer and closer to one another), the very tips of the teeth even surpass the chiton teeth in stiffness!!!

Here are pictures produced through a process called PIC mapping, which shows the size and orientation of crystal fibers at the tip of the teeth.

That feels like it shouldn't be right, no? You'd think that the toughest biominerals in the world would belong to, like, the skull of an animal that rams into rocks or maybe the shell of some animal, not the teeth! The teeth of chitons and parrotfish out of all animals no less! Who would've guessed that the diet of "rock animal" would make the parrotfish require some of the toughest dentition the world has ever seen, huh? That right there is one super good reason why you should never stick your finger in the mouth of one.

Every day I am blown away by how amazing fishes are....

hope you don't mind me adding on but fluoapatite is also found in human teeth *if* you use fluoride toothpaste. use the good stuff and get powerfull parrotfish teeth!

I see! How cool; that's one step closer to becoming a parrotfish!

WHAT DOES THIS MEANNNN TTOTT

FUCK DISCOVERY HERE'S THE 4 SEASONS OF INFINITY TRAIN

being so fr when I say that transmisogyny has put feminism back like 50 years

what i thought we had distanced ourselves from was the reduction of women to vaginas and wombs and the ability to bear children. i thought we had progressed past ‘dresses are for women and pants are for men.’ i thought we progressed past the idea that someone is less of a woman if she does not adhere strictly to beauty standards. i thought we progressed past the idea that naturally being comfortable adhering to highly feminine standards is vulgar. but i (sarcastically) guess no one could have predicted that trans-exclusive feminism would be the downfall of all the progress we’ve made

— Quote by Leslie Feinberg, from TransSisters: The Journal of Transsexual Feminism, issue 7, volume 1. 1995.

This is why I get so tired about “whose a real women” and “are transgender people real” and the like because it’s so irrelevant. We have group or people that have an insane suicide rate and we have a solution that reduces that by an insane amount.

No matter how you slice it no theoretical reason nor gender rhetoric can change the gender affirming care is improving more lives than it’ll ever hurt

i think this belongs here too

all the statistics are massively in favor of gender affirming care no matter how you slice it.

Adding to that last one bc that statistic made me feel nervous post top surgery- post surgical depression is an extremely common response to ALL SURGERY. You feeling really bad in the weeks after gender affirming care does NOT mean you made a mistake or even that you're part of the regret statistic. Those knee surgery and back surgery folks also got it too!!

why yes i do peddle the "senjuro should learn soryuu" agenda! an agenda kyojuro seems very leery about lol. rip him i guess.
