did you know only 1 in 10,000 gar are golden colored? and that i love them sosososososo much? and its my dream pet?
A gar of gold… 42 garats…
Is spider silk being as strong as steel another lie from childhood? Bc you're able to break it pretty easily on accident. Genuinely asking.
spider silk IS actually significantly stronger pound-for-pound than the same amount of steel, but only in one direction! and coincidentally, it's the same exact direction that got a bunch of people killed in a submersible last month.
see, when people talk about the "strength" of spider silk versus steel, they're specifically talking about tensile strength:
which is specifically the measure of the strength of a material when two forces are pulling at it from the ends, like when a steel cable is holding up a bridge support, or crane cargo:
or like when a strand of silk is supporting the entire spider.
that's tensile strength, baby!
but there's another type of strength that's very important to take into consideration when you're actually building things like bridges and submersibles, and spider silk and similar materials like carbon fiber are absolutely garbage at it! and that's compressive strength.
this is basically the inverse of tensile strength, where instead of being yanked at from both ends, the forces are crushing inwards at the material from both directions instead.
you can expect to see these kinds of forces involved in road surfaces, vehicle engines, and again, submersibles.
now steel and its more competent cousin titanium are fucking GREAT at compressive strength! the harder the outside forces are compressing them, the stronger the metals get.
NOT TODAY, FUCKERS
but strand-based materials like spider silk and, again, carbon fiber, are fucking garbage at this. they can take a certain amount of pressure, but each round with compressive forces snaps some of the strands that makes up the material! and those don't grow back, so basically you're just gradually reducing your poor overstressed carbon-fiber hull into a completely useless shell of shattered thread fragments over time as the strands of fiber that actually give it strength die off one by one.
and eventually, something's gotta give! and then people die about it.
this is why, even though spider silk IS stronger than steel in one specific way, we're never going to stop using steel in industrial applications and switch over to spider silk or carbon fiber full time. these materials all have their areas of use, and steel just covers a wider base of applications.
and don't even get me started on shear strength. we'll be here all damn day.
Divergent evolution in plague doctors
(I am nearly certain this has been done before but I couldn’t resist the shoebill stork doctor.)
What’s the best thing about being Lynda Carter
Probably the bees
Yes.
Sabrina. The bees.
Just reblogging for some Oklahoma rep.

not a request
apparently male spiders in many species have evolved a behavior to catapult away from females after sex to avoid getting eaten but then many of these spiders will go back to the same females as before and attempt to have sex with them again 😭
spiders are incredible it’s baffling to me that people hate them. like are you hearing this.
Real talk though: do furries have privilege over scalies because they have more visibility and are more widely regarded as cute?
you can’t. you can’t say “real talk though” and then ask if there’s such thing as furry privilege
BEKKATHYST 10th Business Anniversary Giveaway!
~This giveaway is in no way affiliated with Tumblr.~
Please read thoroughly before entering!
Hello lovely Tumblr folk! It’s that time again- I have a giveaway for you all. This one is extra special because my business/shop turned 10 years old earlier this year! 💜
We have an online store that could use your support!
You can also find us on Instagram.
About us: My business is a small, family-run establishment that I started here on tumblr in 2013. I’ve been lucky enough to grow to the point where this supports me, my partner, and our daughter. In the US we also had a brick-and-mortar shop in which I employed my mom and a few of my siblings. However, we closed it to be able to move to Austria, my home country! 💜 I strived to put compassion and ethics above all else in my business, and I hope that shines through. We have a website but also run many fun sales directly here on Tumblr!
One of our long-term customers graciously asked to sponsor this giveaway, so I'd like to give a huge thank you to @classicintp !! Also thank you to everyone who voted on which crystal should be featured in the giveaway. Opal won in a landslide!
This giveaway will have two winners.
What the first winner receives:
- The two amazing specimens of opal shown above! The darker piece is a boulder opal from Australia with a hole drilled through it (so it can be worn as a necklace) and the lighter piece is a massive rough chunk of welo opal from Ethiopia. The retail value of both of these opals is approximately $650.
What the second winner receives:
- A $50 gift card that can be used for our online store or tumblr sales!
Rules:
- You must be 16 or older. (If under 18 you MUST have parent’s permission)
- You can be from anywhere in the world! I am shipping from Austria.
- Shipping is entirely free, I will cover it. But if you live in a country that charges import tax on gifts, you are responsible for it. If it gets sent back to me, you will need to pay shipping to have it sent again.
- You must be following me, so you can get updates if anything about the giveaway changes.
- Please check out our online shop!
- Reblog this post to enter. Likes count as additional entries. No giveaway or spam blogs. If you reblog on a side blog, let me know in the tags what the name of your blog is that you’re following me with.
- Please don’t spam people with reblogs- limit 2 reblogs per blog per day.
- At the end, each entry will be assigned a number and the winner will be chosen by a random number generator.
- The giveaway ends Tuesday, August 1st, 2023.
- The winners will be messaged and must respond with their full name and address within 24 hours, or a new winner will be chosen.
Please respect me and my rules, and have fun!
Did you guys know that the most recent version of sharks have fins that are kinda leg like and they like to walk up onto land?
no way i must have missed an update!
The Epaulette shark is only about 9 million years old as a species, making it the most recent branch in the shark family. And it is slowly but surely evolving into a land animal
You know what to do boys
Ok y’all brace yourselves cuz I just learned about a new animal
Yes, that is an animal. Yes, scientists refer to it as the purple sock worm. No, that’s not it’s real name, silly, it’s real name is Xenoturbella!
When these deep-sea socks were first discovered, no one knew what the fuck they were looking at (and, really, can you blame them?). They have no eyes, brains, or digestive tracts. They are literally just a bag of wet slop. DNA analysis initially seemed to indicate that they were related to mollusks, until the scientists realized that DNA sample was from the clams they had recently eaten (yes, they can eat with no organs. We don’t know how.)
Scientists then analyzed the data again and tentatively placed them in the group that includes acorn worms, saying that their ancestors probably had eyes, brains, and organs, but simplified as a response to their deep sea ecosystems.
Later DNA testing has since shown that they are their own thing! Xenoturbella, along with another simple and problematic to place creature called acoelomorphs, belong to their own phylum called Xenacelomorpha! This places them as the sister group to all bilateral animals. So, they just never evolved brains, eyes, or organs. They are a glimpse at a very primitive form of animal that never bothered to change, because apparently what they do works. Rock on, purple sock worm.
yeah im “transitioning” *dissolves into tiny pieces as i click to the next slide*
Is there a transfem version?!?
ask and ye shall receive
Nonbinary version?
enjoy 💛🤍💜🖤
