If I could release a patch for human anatomy, it’d include the restoration of a full nictitating membrane. It keeps a falcon’s eyeball from drying out during fast flight, protects vulture’s eyes from all the gore they push into while eating, creates a diving goggle for polar bears and amphibians…We lost our nictitating membrane because we didn’t really need it anymore but I want it back.

(Cats and dogs have nictitating membranes too but they’re usually kept retracted. You may see them if the animal has its eyes open slightly during sleep, though.)

Cool post about the nictitating membrande! I love learning stuff about nature from you:) I had a rescue cat once who had, somehow, damaged his third eyelids. They would often cover half his eyes making him look very funny but he was still a happy and sweet boy. Anyway, your post made me think of him and made me very happy. So thank you!

And thank you! :D

Glad I could remind you of a fuzzy friend. My nictitating-membrane-in-cats experiences have mostly been “buddy, I love you, but when you sleep you look like the undead”.

Sorry for the delay, I’ve been busy with pride events all weekend.

In return please have these sapphic lizards: The New Mexico whiptail is an all-female species of lizard in the southwestern United States. Even in parthenogenesis their ovaries need to be stimulated in order to produce viable eggs – so they perform mating behaviors with the other female lizards.

Cat Claw retraction 

This is such a beautifully done graphic! It shows, really well, why declawing your cat can be so excruciating and disabling for the rest of their life. Notice how the bottom of the 3rd toe bone is mostly what’s weight bearing? If you amputate that bone (which is the most common surgery) the end of that 2nd toe that’s never meant to bear weight will be what your cat puts weight on when it steps. Also, notice how the tendon runs the whole length of the toe? That means when you cut the tendons to that final, amputated digit, you’re going to mess up tendon function in the entire toe. 

This was reposted from @alithographica who does a lot of similarly incredible informational posts about animals.

🙌Thanks astriferal!

Okay heads up for all Americans eligible to vote:

The Supreme Court just issues a ruling allowing Ohio and other states to purge voters from their election registration rolls due to their failure to cast a ballot in previous elections.

This is a major victory for the Trump administration and the GOP, and a direct consequence of the Supreme Court being stacked with more conservative judges (the votes were 5-4). This is also a huge part of what Trump/the GOP were counting on to save them in the 2018 midterm elections, which is where Democrats have been hoping to take back a majority in the House, giving them more power to combat Trump’s abuses of power and Republican legislation.

What this means is YOU CAN NOT ASSUME THAT YOU ARE REGISTERED for the 2018 elections, just because you SHOULD be. Thanks to this decision, red states can purge voters’ registration based on their not having cast a ballot in even just previous federal elections, NOT just the national Presidential elections. Effectively, if you haven’t voted in previous senate races or for congressional representatives in the past few years, that’s all they need now to say you’re no longer registered and need to register again.

They’re deliberately counting on people assuming they’re still registered and so not checking until after registration deadlines have passed, or showing up to vote this November and only then finding out they’re no longer registered, when its too late to do a damn thing about it.

And this is absolutely targeted at marginalized communities, low income voters, disabled voters, and basically anyone who simply can’t always AFFORD to keep on top of every federal election and show up to vote in every senate race, etc. Which not so coincidentally happen to be all the communities and voters who have the most to gain from Democratic victories in the 2018 midterms and are the least likely to cast votes for GOP candidates at this point.

This was absolutely a calculated effort aimed specifically at keeping the GOP in power with a majority control of the government come November, and unfortunately, it has a DAMN good chance of accomplishing just that if it goes by unacknowledged. I’m not looking to alarm or panic anyone, simply to say:

If you are a registered voter in a red state at this point, please please please do not take your registered status as assumed. Check on your registration status, look up all relevant voter registration deadlines for your state and district, CIRCLE THAT SHIT ON YOUR CALENDAR, and check your registration status AGAIN right before those deadlines pass, so you can be sure of it before its too late to do anything about it til the next voting cycle.

use vote.org to check your registration status. use the form, or scroll down to find the resources for the state you live in.
