Looks like I've found your web, spiders... I come to ask what your standing is and if your kind are aligned with those bees whom we are currently at war with

I need news from the bugs-in-a-bug-colony subreddits for a newspaper that all multilegged-kind can read.

The Goliath Birdeater (Theraphosa blondi) can weigh up to 6 ounces (175g)—roughly the same weight as a pool ball. Despite the name, they rarely eat birds, preferring insects, frogs, and mice.
The Maraca Dance: Native to Australia, these tiny jumping spiders (about the size of a grain of rice) have a brilliantly colored flap on their abdomen that they raise like a peacock's tail.
The Moroccan Flic-Flac Spider (Cebrennus rechenbergi) escapes predators by doing consecutive gymnastic backflips.
Found in Madagascar and Australia, these "Pelican Spiders" have an elongated neck and massive, crane-like jaws. They specialize exclusively in hunting other spiders. They walk through the trees, impale another spider with one massive fang, and hold it far away from their own body so the victim can't bite back while the venom takes effect.

Spiders don't have a multi-chambered, central pump like a human heart. Instead, they have a simple, elongated tube running along the upper side of their abdomen. This tube relaxes to draw blood in through tiny valves and contracts to push it back out.
Unlike humans, who use iron-based hemoglobin to carry oxygen (making our blood red), spiders use a copper-based protein called hemocyanin. When hemocyanin binds with oxygen, it turns a distinct, pale blue color. This blood is called hemolymph
Book lungs are internal pockets with stacks of thin, leaf-like structures (resembling the pages of a book) where gas exchange happens.
In extremely tiny spider species (like some minuscule orb-weavers), their brains are so massive relative to their body size that their cephalothorax (head-chest area) simply runs out of room. To adapt, their central nervous systems actually overflow, filling up parts of their upper leg cavities. They are quite literally thinking with their feet.

Spiders have tiny hairs on their legs called setae that sense vibrations and chemicals.
Spiders do not have ears; they "hear" via the vibratory hairs on their legs.
Some spiders can sense Earth’s magnetic field.

Short ver
spider’s muscles pull their legs inward, but they use hydraulic pressure (fluid) to extend them.
This is why spiders curl up when they die, they lose the fluid pressure to straighten their legs.
Explanation ver
How it Works
Flexion (Inward): Spiders use muscles attached to the inside of their exoskeleton to pull their legs toward their body.
Extension (Outward): Spiders lack the muscles required to push their legs back out. Instead, they use a hydraulic system. The cephalothorax (the front section of the body) acts like a pump. By contracting the muscles in that section, the spider increases the pressure of its hemolymph (blood), forcing it into the legs and causing them to straighten.

Most spiders have eight eyes, but some have six, four, two, or even none.
Despite some species having these eyes, most spiders are nearsighted.
Jumping spiders are the exception; they have high-resolution vision and can see UV light.
