"Spiders" is too broad to use as a topic. Let me cut it into easier details.
Common spiders: Most of these are web-creating. They depend primarily on this. Anything bigger than them is too much of a threat for their fangs to deal with. . Common spiders use small fangs, webs and maybe venom to defend themselves.
Tarantulas: Tarantulas have five key aspects to what they are
1. They have finger-like spinnerets for creating tripwires.
2. They have small hairs which can irritate the skin of a predator.
3. They have retractable claws like a cat to aid grip.
4. They have non-venomous fangs to kill.
5. They ALL have eight eyes to see around them.
Some species have several of these, but only tarantula have all five. A soider missing one of these is not a tarantula.

While spiders can exhibit certain behaviors based on conditioning, training them to defend a person is not feasible. Spiders lack the cognitive ability to understand or respond to commands like a dog would, and their instinctual behaviors are primarily driven by survival and hunting. Additionally, most spiders are not aggressive towards humans and would not recognize a need to defend. Therefore, relying on a spider for defense is impractical.
All spiders are venomous - they use their venom to disable their prey, and defend themselves from predators. Not all spiders have large enough fangs to bite through human skin though, and not all spiders have venom that is dangerous to humans, and most spiders will run away rather than bite you, if they can.
Spiders eat most of an insect. Some spiders are capable of chewing up the entire body of whatever it has caught, flooding the chewed up mass with digestive fluid, and then sucking up the digested food. Other spiders are not capable of chewing up the exoskeleton of a prey item, so they inject digestive fluids into the body, let the contents of the exoskeleton digest, and then suck that up.
spiders defend their self by biting the person or thing their bites could make you go to the hospital that's how bad their bites are you don't want to mess with them boy the can be nice insects sometimes but don't you ever mess with them ever ever ever ever.
