living mosaic

we fucking knew it. vindication. also phil babe what happened to the flash drive...

Every year, we can remember everyone who chose to believe that equality is possible, that the "same old stupid plan" must be fought with all we have, and dedicate ourselves to living that every day, to carrying our quiet part in the battle to create what Lincoln called a "new birth of freedom."

These photos show the embryonic form of Limulus polyphemus, commonly known as the Atlantic horseshoe crab. The eggs of this species are initially opaque, with a grayish-blue, green, or pink coloration, but they become increasingly translucent as the embryos mature, providing a glimpse of the tiny horseshoe crabs developing within.

The legs become visible roughly five days after fertilization, and the embryos begin to move shortly thereafter, eventually flexing their legs and twirling their bodies. They molt for the very first time just a few days later. Each embryo will shed its skin and grow a new one four times in total before it even hatches from the egg.

The hatchlings finally emerge after 2-4 weeks. The freshly-hatched larvae measure less than 1cm long, and they look just like miniature versions of their adult form, except that they do not yet have tails (which are actually known as telsons) and their exoskeletons are still soft and translucent. These young horseshoe crabs are often described as "trilobite larvae."

Atlantic horseshoe crabs generally spawn in May and June, with hundreds of thousands of individuals gathering along the coast on the night of the full moon and new moon. Each female lays up to 100,000 eggs per season, but very few of those offspring actually survive to adulthood. Most of the eggs are eaten or destroyed before they can even hatch, and many of the remaining larvae perish at some point during the 10 years that it takes for them to reach full maturity (i.e. the age at which they begin to reproduce).

Wild horseshoe crabs can live to be more than 20 years old, and they can measure up to 60 centimeters (2 feet) long. They have 10 eyes in total, including two compound eyes that are specifically adapted for the purpose of finding a mate:

The most obvious eyes are the two lateral compound eyes. These are used for finding mates during the spawning season. Each compound eye has about 1,000 receptors or ommatidia. The cones and rods of the lateral eyes have a similar structure to those found in human eyes, but are around 100 times larger in size. At night, the lateral eyes are chemically stimulated to greatly increase the sensitivity of each receptor to light. This allows the horseshoe crab to identify other horseshoe crabs in the darkness.

Horseshoe crabs have been around for at least 445 million years, which means that these creatures are about 200 million years older than the dinosaurs and at least 50 million years older than trees, and yet their morphology has changed very little in that time. In fact, modern horseshoe crabs are frequently described as "living fossils," because they still look strikingly similar to their fossilized ancestors.

It's important to note that horseshoe crabs are not true crabs. In fact, they're not even crustaceans -- they belong to a completely different group of arthropods known as chelicerates, and they are more closely related to spiders and scorpions than they are to crabs.

i know so many people who were/are at the mercy of very terrible people because they literally have no other options. it's harrowing especially since ive been there.

This, too, is a trashed bathroom; young queer people living through hell and having precious little control over their circumstances or the world in which they exist can affect something by using the language of social justice as a cudgel on their would-be allies, as well as getting a brief feeling of power over someone else by doing it.

This kind of attitude pisses me off btw. Actually when it comes to politics, we should be thinking about stuff seriously basically all of the time. It's not about being virtuous or morally superior or whatever, it's just important to care about what you are saying. I don't care that lots of dog people say there are "gender" differences in dogs – lots of people say lots of bullshit and if it's wrong and harmful it should be addressed.

Hey sorry no you can't think about "dog genders" without thinking about human gender because gender is a social construct that doesn't apply to dogs so you've already failed! Fuck off with your dismissive "looool".

1.) Not all our parents would bake us a fucking cake when we come out. Some of us are closeted. Surely you understand this? You also do not need to know my parent’s names or occupations; we are both adults. I do not need nor want to mix you and my private life with my parents and my public life.

2.) Trans people do not owe you their dead name or government name

3.) I’m not telling you for the sake of job security. I am a government fucking caseworker working amidst a fucking lavender panic!

“There’s no way you’re a different person outside this; you’re still you at your core. What harm is there—”

No, I am a completely different person. A different person with a different personality and different interests and a different name and presentation. I am a completely different person because I keep this life and my public life private to avoid fracturing 90% of my interpersonal relationships and 100% of my professional ones.

“You’re not out? But you’re so confident.”

I need y’all to start bringing that energy. Because it’s not always safe for someone to be out and not everyone is safe to be out around.
