All "Arachnids" have eight and only eight legs. Any spider is a member of the Arachnid family.
What is the most dangerous spider?
This comes from http://eyespybc.tripod.com/darksideonlinetabloid/id17.html
According to the Guinness Book of Records the worlds most venomous spider is the Brazilian Wandering Spider.
This spider is believed to have the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006mg (0.00000021oz) is sufficient to kill a mouse.
The Brazilian Wandering Spider is very fast, extremely venomous, nervous, and aggressive. This large and dangerous spider is grows to five inches long, and is ranked among the most venomous spiders known to man.
This Spider is often referred to as the "Banana Spider" because there have been cases where these spiders unintentionally appeared on banana boats heading for the United States from tropical, and subtropical regions of South America.Tarantulas are commonly found during banana inspections.
This is not the first time deadly spiders have made it across Canadian borders from tropical regions,a and may occur more often than realized.
The problem arises when some of these spiders manage to go unnoticed and begin weaving their webs in our unsuspecting neighborhoods.They can breed and proliferate until they cannot be controlled.
British Columbia, and particulary Vancouver Island has already been invaded by at least two other deadly spiders, which are now considered to be permanent residents.
The deadly Brown recluse (Violin), and Hobo spiders. Reactions to bites from either of these two spiders is very similar, causing tissue breakdown.Amputation of the affected areas are often required. Death can follow.

How long for spider eggs to hatch?
It should take a few days or weeks, months at the max.
Improvement: I've been keeping an orbweaver spider for the last week or two and she made her nest about 5 days ago. I'll try and get back to this board when they hatch.
I copied this answer from Yahoo
Most crab spiders will have two successful hatches of eggs every year. Once the eggs are attached, the female will stay within the vicinity, like you are already observing. The time it takes for the eggs to hatch is based on several parameters, the most important being temperature. The best option in captivity is not to alter the temperature too drastically. Maybe place a small lamp near the eggs and keep them at room temperature, but turn off the light at night to better mimic natural conditions. It could be anywhere from 2 weeks to a month, but probably closer to 2 weeks.
Once the eggs hatch, the young spiderlings are still soft and fragile, and usually will not start eating each other for about 2 days or so....this is not always the case, but as a general rule, they typically need at least a day for their tiny exoskeletons to harden before they start searching for a meal. Your best option is to leave them for a day, and then release them, once outside they will disperse on their own.
You can hold onto your female because she may not be done laying eggs, many spiders are capable of storing sperm for long periods, and she may be able to producer another clutch of eggs, especially since you mentioned she is eating well.
How long have spiders been around for?
The main groups of spider developed about 200 million years ago, in the Triassic period. Spider-like arachnids are known from towards 400 million years ago, and some true spiders are known from about 300 million years ago in the Carboniferous period.
The spiders are part of the Arthropod family, which dates back to the Cambrian era, 500 - 600 million years ago.
Nope. All spiders live solitary lives and even die before their young can hatch hatch. There's never been such thing as a colony of spiders except for the ones who follow Aragog. 😉
What does the yellow bellied sapsucker eat?
It is a type of woodpecker, but what's different about this "woodpecker" is that it eats sap found in trees. normal woodpeckers usually eat insects, but unfortunately, the yellow-bellied sapsucker is a bird who can kill trees by sucking all the life out of them.

How can you tell if a tarantula is dead?
How the tarantula dies is on the care you give it (or lack of) and could be from old age. When the tarantula dies (majority of the time) it curls up in a little ball. When it lays on it's back, it is not dead!!! It is only molting and should get up in a couple hours. Molting is when they shed their skin in order to grow and get bigger! Good luck!

How do black widow spiders breathe?
Black Widows
(species Latrodectus mactans, Latrodectus variolus, and Latrodectus hesperus) "breath" through book lungs, like almost all arachnids.
Book lungs
are passages on the underside of the abdomen that draw air over membranes that allow for gas exchange. Hemolymph (Spider blood) then picks up the gasses and transport them throughout the body through veins and arteries where they are absorbed by the organs and muscles. The hemolymph is circulated by a thin tube on the top of the inside of the abdomen that contracts to pump the fluid through (it's a form of a heart)

How does a toad spider look like?
Most true toads (family Bufonidae) are poisonous. Bufonids are generally large, brown, warty and rather ugly. Behind the eyes, on top of the head, are two large glands called paratoid glands, and these secrete a toxin known as bufotoxin (it also has several other names.) The larger the glands the more toxic the toad, generally. There are no other identifying factors. Poisonous frogs, particularly the batrachid frogs (Phyllobates, Dendrobates, Epipedobates species amongst others) are generally brightly coloured. Throughout nature, this signal means, I don't have to hide from you because I'm poisonous. Don't eat me.
Well they are brownish. they have big chubby cheeks where they keep their poison they are all different sizes. But other than all that they look like frogs
Some toads are poisonous, but most aren't.

When studied under a powerful microscope, Chinese scientists have discovered that their legs are thousands of tiny hairs, each about 50 micrometers long thread.This ruffled the feathers out tiny beams of silk, "trap" into the air and creates aseparate buffer spider legs with water, and increase the buoyancy of the animal.
How do spiders eat if they cannot chew?
As far as I know, the answer to this question depends on the type of spider you are referring to. Some spiders can eat solids. So, they simply bite and chew. While other spiders can not eat solids. These spiders will inject their prey with venom, and the venom liquefies the insect's insides. The spider will then essentially "drink" it's food.
Could a spider live in hair nose mouth?
No. Your brain is encased in a fluid, so the spider would drown and there is no food for a hungry spider to eat. Spiders cannot live in the nasal passages because it is too damp, mucus would almost immediately trap and drown the spider. There is also no edible food in the nasal passages for the spider to eat.
