5.Crushing

Spiders are soup eaters. Once a bug gets tangled in a web, the itsy bitsy spider will come along and inject it with venom, both to kill it and to begin the digestion process by turning its insides into a smoothie. However, uloborid spiders are unique in that they don’t have venom glands. That should mean that they’d have to wait for their victims to die of starvation or boredom before it’s safe to get close to them (you don’t want to risk getting stung by a bee while you’re trying to drool digestive juices over it). But spiders aren’t really known for their patience. Since uloborid spiders can’t intoxicate their prey, they use other, less humane ways to deal out death. They repeatedly wrap a captured insect in webbing, over and over and over, sometimes for as long as an hour. After, oh, around 28,000 loops and 400 feet of silk the bug is dead, either through suffocation or because it’s been crushed to death in the ever-tightening cocoon. Uloborids use their webbing to create a straitjacket of death. They’re like the pythons of the arachnid world.

4.Net Casting

Most spiders are content to wait. These couch potatoes of the arachnid world weave an intricate marvel of nature, and then sit there hoping a dumb bug stumbles into it while they kick their feet up. Ogre-faced spiders do things completely differently. They’re the daredevil, X Games–loving, Red Bull–swilling, adrenaline addicts of the arachnid world. First, the spider makes a net. Not a web, but a non-adhesive elastic net that it holds in four of its legs. That’s why one of its other names is the “Gladiator Spider”—because it’ll launch itself at bugs and try to entangle them in its net. And when it’s not using its net to entangle helpless passersby, it’ll hang the thing up. It’s a spider that not only makes and wields its own weapon, but that has a closet to keep it in.
But the ogre-faced spider isn’t just running around trying to entangle random bugs. No, there’s a system. Hanging head-down over a popular insect path with its net, this hunter will also mark the target area by releasing fecal droppings that dry white. Any bug that passes next to the spider poop is in the kill zone. How fast can the net-wielding arachnid move? One strike was clocked at one-thousandth of a second.

3.Sex

Xysticus cristatus is a crab spider with peculiar tastes in the bedroom. Spider mating is pretty dangerous for the most part. Females are typically bigger than the males and they’ve been known to snack on their boyfriends. Several species have interesting mating habits, from dancing and stroking to gift giving and, of course, murder. As varied and exotic as arachnid courtship can be, Xysticus cristatus is pretty unique. To start off their night of passion the male runs up and grabs the female by the leg (which is a pretty gutsy move in and of itself). She freaks out a little, but gradually calms down. The male spider then caresses her with his legs while he uses his silk to tie her up. Yes, some spiders are into bondage. The female spider doesn’t fight or struggle as he secures her, even though she could break free of the silk if she wanted too. In fact, after the male spider has done the deed, he just leaves her there, tied down to whatever leaf or stick they were using as a love pad. It’s up to her to get loose. She easily does, but only once the male is finished. It’s the spider version of 50 Shades of Grey.

2.Webbing Shooters

Everyone loves Spider-Man, right? The way he leaps around insulting and beating up the bad guys with his spider-themed superpowers. The only problem is that none of his abilities are realistic. There is no psychic spider sense, arachnids don’t just magically cling to any surface while wearing footy pajamas, and most importantly, spiders don’t have web shooters. That’s completely implausible, right? No spider can hurl webbing through the air at an opponent . . . with the single exception of spitting spiders. They actually have web shooters that put Spider-Man to shame.
All spiders eject silk from a spinneret that’s found on their rear. But arachnids of the Scytodidae family have developed a nifty trick that few others can match. They can shoot sticky silk out of their fangs. And they don’t just dribble it out, they launch it out of each fang like a Super Soaker. They can immobilize prey with their web slingers, just like Spider-Man. They can even alternate between firing one or the other (or both) at the same time. The only real difference is that the spider’s fang webbing also has the added benefit of being venomous. So they fling toxic webbing out of their faces. Beat that Spidey!

1.Climbing Socks

To climb up walls, most spiders use over 600,000 tiny hairs located on the bottoms of their feet. These hairs are so small that they can grab hold of a surface using molecular forces (the van der Waals force is an electrostatic force that acts between two molecules that are within one nanometer). This is how spiders can walk up virtually any surface.
But that doesn’t explain larger arachnids like tarantulas. How do they get around? Tarantulas are too big to cheat physics with magic hairy static-cling feet. So they came up with another method that you may have heard of already in this list—spider silk. Tarantulas can squirt microscopic strands of silk out of their feet. By putting a tarantula on a clean sheet of glass and then trying to shake it off, researchers were able to find splatters of webbing where its feet were. At first other spiderologists were doubtful—There was no way spiders could shoot webbing out of their feet. Out of their butt? Sure. Out of their fangs? Sometimes. But web slingers built into feet just seemed dumb. Until scientists looked at the feet of a few dead tarantulas under an electron microscope and proved it. They found special spigots with silk coming out of them. Tarantulas have little silk nozzles right on the bottom of their walking nubs that helps them climb surfaces they ordinarily shouldn’t be able too. So basically, spiders can expel silk from just about any part of their body.
