All Spiders (with one or two exceptions) are venomous, it is necessary for them to feed, as they cannot eat solid food. There are two groups of spider which are commonly referred to as 'crab spiders', one is the Genus Sicarius, whose venom is dangerous to humans. The unrelated spider family Thomisidae is the other group, these are not dangerous to humans.
No crab spiders do not make webs they are just like normal crabs but someone just gave it the name crab spider because they wanted to spook people but it never worked unless you panick about it the person who gave the crab spider its name is called Gargwanyai Helemgui.
Most spiders do have venom but often it is not poisonous to humans. There are some spiders without venom at all like orb spiders.
yes,but they are harmless to humans their bite will hurt though
yes it is because spiders are carnivores so a spider crab is
no, they both make the same
spiders make spiderwebs so that when a fly flys by it flys into the web which is very sticky so the fly cant get out. the spider then wraps it up then sucks its blood for dinner.hunting spiders dont make webs.
They know by instinct, different spiders pick different habitats to live in.
because they have some kind of oil inside them that helps them not stick because they have some kind of oil inside them that helps them not stick
No. They do not prefer any compass direction. Some spiders make webs that face up. Many spiders make webs near to porch lights because these lights attract insects. Where the web goes, and which direction it faces (if it is not a messy tangle web like that of the black widow spiders) generally depends on where the spider can find appropriate supports from which to hang its web.
no, they both make the same
When ever they want to . But some do not make webs
Spiders make unique webs because they do not want other spiders coming into their webs. They have a unique shape, design, and scent to keep other away.
NO

no, but SPIDERS spin WEBS.
If by "redback spiders" you mean the kind of widow spiders that grow in Australia, they make the same kind of three-dimensional tangled filament webs that all the member of their Family make. Some other kinds of spiders make orb webs, sheet webs, etc.
