Why are spiders also called arachnids?
it was once in italy where if a big spider bit them they have to do a dance called the tar an tula.
And then the tarantula was named.
the spider isn't as big as a actual tarantula from the americas.
So there you have it.
Your welcome
Are scorpions a type of spider?
Spiders form a monophyletic group with all modern spiders sharing a common ancestor. This means that all spiders are equally related to scorpions. Some stem groups may have characteristics that are plesiomorphic or "primitive with respect to other spiders" that may make them appear superficially similar to ancient arachnids.
What are facts about people with no legs?
People with no legs can adapt to various mobility aids, such as prosthetics, wheelchairs, or crutches, allowing them to navigate their environments effectively. Many individuals with limb loss lead active and fulfilling lives, participating in sports, arts, and other activities. They often face challenges related to accessibility and societal attitudes but can also inspire others through their resilience and achievements. Advances in technology and rehabilitation have significantly improved their quality of life and independence.
Latin name: Lepthyphantes minutus
Size: Between 3mm and 4mm
Distribution: Found throughout the UK.
Months seen: May to November.
Habitat: Tree trunks, old bird nests and sometimes in houses. Builds a small sheet web.
Food: Tiny insects.
Special features: Despite its specific name 'minutus' is one of the largest money spiders, or which there are around 20 species (though recent taxonomic work suggests the genus should be split into smaller groups).
Lepthyphantes minutus is the only one of this genus which has an all-dark carapace and banded legs, making it recognisable in the field.
It is widespread and common, sometimes coming into houses, but usually found in dry microhabitats such as the litter caught in epicormic growth on tree trunks, old bird nests etc.
The genus as a whole contains several of our commonest spiders. The much smaller Lepthyphantes tenuis which has claim to being THE commonest spider in Britain.
Are barn weaving spiders poisonous?
Like all spiders, a barn spider is poisonous, but not usually particularly harmful to humans. The bit of a barn spider may cause some swelling and redness for a day or two, but it is unlikely to cause a human or an animal to become ill.
How do spiders lay their eggs?
"Different spiders mate in different positions, but in all cases the aim is to transfer sperm from the male to the female. The male does this by inserting the mating organ at the end of its pedipalp (a spine-like structure on tip) carrying the sperm, into the female's reproductive (epigynal) opening on the underside of her body. In some species the tip of the pedipalp will break off during mating or a hardened secretion will block the females openings, preventing other males from mating with that female. The sperm is stored in sacs inside the female's abdomen until she is ready to lay her eggs."

And please remember we are NOT mammals, the bible tells me so. in Genesis 1:27, does it say anything about us being mammals NO!& teachers just have to teach the students that we are mammals! The guy that came up with us being mammals, well that guy didn't even believe it was true! There is nowhere in the bible that says we are mammals!
All spiders are venomous, since they cannot constrict their prey, they have to have venom to allow them to paralyse and digest their food. The only reason people do not think some spiders such as house spiders are not venomous is because people do not get bit by them, simply because their fangs are not big enough to penetrate human skin. So yes, jumping spiders are venomous.
Which is more dangerous funnel web or black widow spider?
No. The funnel web spider makes a web in a funnel shape (obviously), but the black widow hunts for its food. :)
some people say they are but really they're not its just like a bruise......not dangerous at all
Can brown recluse spiders lay eggs in people?
No this is pure myth and urban legend. Brown recluse spiders have a necrotic venom that kills tissue and will cause an abcess at the site of the bite that requires medical care, but like all other spiders create egg sacs in dark secluded dry areas, usually between April and may. They do not lay eggs in people.
I have a friend who was bit by a brown recluse spider in the middle of her back .. It's been about 2 or 3 months ago since this happened, If you don't believe it her name is Lorie Daughterman and she lives in STANEY MONTANA.. first the doctors were pulling eggs out of her back for about a month…THEY WERE using a syringe to get the eggs out. And now they are starting to pull out little baby spiders but they can only pull out so many at a time, so when she is sleeping the little spiders come out of the hole where she was bitten…this has been going for more than a month…to bring you up to date as of April 4, 2015 they have pulled all most full grown spiders out of those same 2 holes and they are sending them to Denver to analyze the spiders.. she has new bites from the baby spiders and it seem they are laying eggs too.. On april 8, 2015 they are going to hopefully get them all out of her… she been struggling with this the whole time and she heck of a trooper… I put this out there so others can be aware of this AND MAYBE SOME ASSOCIATION MIGHT BE ABLE TO HELP HER WITH ALL THESE BILLS THIS HAS CAUSED, AND TO MAKE OTHER PEOPLE AWARE WHATS OUT THERE AND TO BECAREFUL OF ALL SPIDERS!!!!!!
What body parts does spider use to get food?
Spiders hold their prey with their legs. Spiders inject venom to paralyze their prey with their fangs. Spiders regurgitate fluid from their stomach's onto the prey and the fluid breaks down the nutrients which flow into the spider through its mouth. (We humans have internal processes for getting nutrients from food, spiders have external processes.
Is the largest spider extinct?
Back in the Dinosaur ages (around 300 million years ago) there were huge spiders like the Megarachne servinei which had a leg span of over 50cm. But well obviously there not around anymore.
However there are still huge spiders, like the Goliath Bird Eeating Spider which has a leg span of around 3ocm.
Hope this helps :)
No, spiders can't fly. But young spiders will climb up grasses and bushes, stream out a line of web filament until the wind catches it and carries off the spider through the air to a new location.
Is the daddy long legs spider the most deadly spider?
According to urban legend, daddy long-legs produce the most potent venom of any spider, but their fangs aren’t strong enough to penetrate human skin. This isn’t true.
The name "daddy long-legs" is used to refer to several species, including some spiders, but none of them are particularly venomous. When you think of "daddy long-legs," you’re probably thinking of one of these creatures:
- Pholcidae - Spiders in the Pholcidae family are found throughout the world, and they frequently build their messy webs in attics, crawlspaces, and other undisturbed areas. They’re also known as cellar spiders.iStock.com/johnandersonphoto
Pholcidae are not dangerous to humans. Their fangs are short, but capable of penetrating human skin. A 2019 study published in Frontiers in Ecology and Evolution found that the "effects of bites on humans and other mammals are inconsequential."
However, Pholcidae seem to have different peptides and proteins than those found in other spiders' venom; this could explain why Pholcidae regularly prey on spiders that are far more dangerous to mammals. Some Pholcidae, for instance, prey on spiders in the Black Widow family.
That’s one possible explanation for the myth—someone saw a Pholcidae preying on a dangerous spider, and incorrectly assumed that this meant the Pholcidae was more dangerous to humans. Alas, nature doesn’t really work that way.
"Documented bites on humans make clear that while these spiders can bite, the typical result is a mild sting with no long-lasting effects," the study’s authors wrote.
Of course, ethical issues prevent scientists from subjecting people to spider bites, so most of what we know about Pholcidae bites comes from chemical analyses and anecdotal evidence. One such piece of evidence: In a 2004 episode of the Discovery Channel show Mythbusters, host Adam Savage intentionally agitated one of the spiders and was bitten; he reported a mild burning sensation that lasted a few seconds.
- Harvestmen - This common name refers to Opiliones, an order of scavenger arachnids found worldwide. They’re frequently found in damp, undisturbed areas, but they do not build webs. Opiliones have eight long legs, but they’re not technically spiders. They have no venom glands of any kind.iStock.com/Filippo Carlot
Harvestmen do not have fangs; instead, they have chelicerae, which they use to grasp their food. On most species, these appendages are small and not capable of breaking human skin.
- Crane Flies - These insects are certainly the outlier on this list; they’re not spiders, and they don’t look anything like spiders. They have six legs, wings, and an adult lifespan of about 10 to 15 days.iStock.com/Ines Carrara
Crane flies don’t have jaws or venom, so they’re completely harmless to humans. In some parts of the world, their larvae is considered a delicacy.
In case you’re curious, the most venomous spider in the world is probably Atrax robustus, according to Guinness World Records, which defines “most venomous" as “most toxic to humans.” Atrax robustus is better known as the Sydney funnel-web spider, and it’s native to Australia (where else?).
iStock.com/Ken GriffithsFor primates unlucky enough to suffer a bite, 0.2 milligrams of venom per kilogram of body weight is a fatal dose. The good news: There’s an effective antivenom, and no fatalities have been recorded since the antivenom’s introduction.
No spiders do not take baths because thay can only spend so long in water and the longest time is 1 hour 45 muintes. By the way this is a stupid question. :-)
What spider looks similar to a brown recluse?
the brown reclus cause if it bites you your organs can rearrange
...and that's about the most stupid answer I've ever seen.
Actually, a black widow's venom is a "neurotoxin," which means it effects the nervous system of the body. It's meant to completely paralyze their prey, and eventually kills them as well... but the venom is strong enough that it can seriously effect humans. Young children, elderly, and those who are weak in health can easily die from the effects of a black widow bite. The neurological effects include extreme nervousness, jitters, sweating, and aching joints, as well as nausea, vomiting, and extreme fatigue. A healthy adult can usually survive a black widow bite if not treated, but it won't be a pleasant recovery. However, just as some people are allergic to bees and ants, a healthy person could have an allergic reaction along with the other symptoms, which could surely kill them, so it should never be ignored.
There are also cases of plumbers, construction workers, air conditioning techs, and other high risk jobs that run into black widows constantly, that build up an immunity to their bites to the point it's no more than a bee sting to them.
A recluse's venom, however, has more of a dissolving effect. Actually, most spiders' venom does this, as it dissolves the innards of whatever it's trying to eat, and the spider "drinks" their prey, leaving only the hollow shells you sometimes see hanging in spiderwebs. But a recluse's venom is overkill. When a human is bitten, the dissolving effect can continue to the point of requiring amputation of a limb if ignored, or death if it's not eventually treated, regardless of the health of the victim.
As for which is deadlier overall.... It's literally a matter of "pick your poison..."

What would you do if you were bitten by a venomous animal?
I have a cat at home, and I have been bitten many times. Just wash it, put some cream on it, and keep it from bleeding. A household cat is unlikely to be carrying any harmful diseases.
If you have been bitten by a cat that is no your own, wash the wound (if there is one) and cover it. Most cat bites should be harmless, but it may be wise to let a doctor check it out regardless.
Technically, spiders are not bugs since they are not insects. Not even all insects are bugs. Only insects belonging to the order Hemiptera are bugs.
Although, bugs may refer to any small creature with more than 4 legs. So it is possible; but Spiders are definetly not insects.
Okay, here are some quick facts. The term bug is defined as and insect or small arthropod. Arthropods include insects, arachnids, and crustaceans. Therefore, spiders are bugs. I have no idea why this is a debate when there is something called a dictionary to tell you what words mean.
Which group does the spider belong?
I'm not sure how you mean "Group." Spiders are all members of the order called Araneae and above that in the class called Arachnida.
Most spiders are solitary animals that approach other spiders only to eat them, to fight with them (males of certain species), or to mate. Mother spiders keep their young with them for a shorter or longer period of time, depending on the species. After the baby spider's original store of nutrients becomes exhausted and the babies become hungry, they would cannibalize each other if they were not to disperse.
There are a few species that tolerate close proximity. Some spiders exhibit a great difference in size. The females are huge in comparison to the males. In these species, a female will often tolerate a male to live close by.
In the case of species of spiders that tolerate close proximity of females and may make a sort of group web in which each spider patrols its own part, the group of spiders is called a colony.
