Arachnids
Arachnids are members of a broad class of organisms that are very familiar to humans. The organisms in this class range from the common spiders to scorpions to ticks and mites. However different these organisms are, they all share one common characteristic, they all have eight legs. Questions and answers about the class and the organisms in it should be placed in this category.

Can spiders survive in the snow?
While different species of spiders have different levels of cold tolerance, most spiders cannot survive in snowy conditions. Extreme cold temperatures can cause spiders to become immobile and eventually die due to their inability to move or find food. Some spiders may seek shelter in underground burrows or within buildings to survive winter.
How long can an unfed female black widow live in a glass jar with tiny holes in lid?
An unfed female black widow spider can typically live for several weeks to a few months without a food source, depending on environmental conditions such as temperature and humidity. However, it is not recommended to keep them in a glass jar with tiny holes in the lid as it may not provide adequate ventilation or space for the spider's well-being.
Why are there no dangerous spiders in the UK?
There was never any evolutionary pressure, that made more potent venom more advantageous.
Producing more powerful venom has a metabolic 'cost' to the spider, ie, it takes more energy. Because spiders in the UK prey on small insects, stronger venom gives no advantage, it's a waste of energy. Natural selection therefore favours spiders with a less potent, more energy efficient venom.
Are male black widow spiders poisonous?
Experts in the field have suggested that males (smaller, and sometimes grayish) very rarely bite humans, and their venom is not as potent as the female. This applies to both the northern and southern Black Widow species, latrodectus variolus and latrodectus mactans.
How do all members of the Phylum Ciliophora move?
Members of the Phylum Ciliophora move using cilia, which are short, hair-like structures covering their surface. These cilia beat in coordinated patterns to create movement by either propelling the organism through the water or generating feeding currents to capture food particles.
What is an arachnid other then a spider?
An example of an arachnid other than a spider is a scorpion. Scorpions belong to the arachnid class and are known for their distinctive lobster-like appearance with a segmented tail that ends in a venomous stinger.
Nope -- Fleas are Insecta, Order Siphonaptera. Arachnidae is mostly spiders, scopions and ticks.
How can you tell the difference between a mosquito bite and a chigger bite?
Because a bee sting is bigger than a spider bite
What preys on Black Widow spiders?
A few wasps can sting and paralyze, before eating the Black Widow. She is also a favorite food of the Praying Mantis. Some birds will eat these spiders but could end up with an upset stomach from her poisons.
The only turtle that I have heard about that is able to climb trees is the musk turtle (stinkpot) it climb trees that are overhanging the water they are in usually because of a flood but there are other reasons they evacuate the water.
No.
The only way to tell which spiders in your area are seriously venomous is to learn to identify them individually. If you are in the USA all you really need to worry about are the widow spiders and the recluse spiders. There are a few widow spider species, and the ones that have bites that used to kill adults (before antivenoms were invented) are all glossy black with some red (sometimes an hourglass pattern) on the underside of their abdomens. There is only one species of recluse spider that you need to worry about, that is the "brown recluse," and it is a very undecorative brown color. People are always confusing one or another kind of spider with that kind, and the only way to learn to identify them is to get some good photographs and descriptions. Unlike the widow spiders, the range of the brown recluse spiders is fairly limited, so you also need to find out from your state government wheher your locality even has them.
If you live in Australia you already know about the Sydney funnel-web spider, and you probably know that it is a dull dark brown color. If you live in South America you probably know about the wandering spider found down there that can kill you if you manage to put your foot in your shoe after the spider has gone in and it bites you to keep from getting squished. It is mostly brown too, and certainly not yellow and black.
The spider that comes to mind when you say "yellow and black" is a beautiful spider that weaves orb webs and is never a problem for human beings.
What kind of spider has a black body with white dots and is found inside the house?
The "daring jumping spider"! Although they can jump quite well, they are harmless. They are found quite commonly in houses and prey on smaller insects.
Mature female hobo spiders are 9.5-16.5 mm (3/8-5/8˝) long, and male hobo spiders are 7-13.5 mm (9/32-9/16˝) in body length. Males have enlarged pedipalps located near the mouth, resembling short legs (Fig. 3.). The hobo spider greatly resembles certain other members of the funnel-web spider family which are harmless or cause minor bite reactions. For this reason, identifications of suspected hobo spiders should be confirmed by an entomologist or other persons trained in spiders.
What kind of spiders are large red with black stripes?
It is also called a Black and Yellow Garden Spider, Argiope aurantia, the spider from Charlotte's Web. All spiders have venom, but very few will bite people and even fewer are dangerous. The Garden Spider minds its own business and stays in it web. It is not aggressive. - http://www.whatsthatbug.com/2009/08/20/19208/
Yes, whale lice belong to phylum Arthropoda - the arthropods. They are crustaceans, more like a kind of shrimp than the insect class to which most familiar lice would belong.
No they don't. A spider has 2 body parts but an insect has 3 =)
What are the features of an arachnid?
The features of an arachnid are its eight legs.
Arachnids are a class (Arachnida) of joint-legged invertebrate animals in the sub-phylum Chelicerata. All arachnids have eight legs, but some exceptions are of some species having the first pair legs convert to sensory function and harvest mite larvae have only 3 pairs of legs.
It is commonly understood that arachnids have four pairs of legs, and that arachnids may be easily distinguished from insects by this fact (insects have six legs or three pairs). Arachnids generally have a total of 6 pairs of appendages - two pairs of which have become adapted for feeding, defense, and sensory perception. The first pair of appendages, the chelicerae, serve in feeding and defense. The next pair of appendages, the pedipalps have been adapted for feeding, locomotion, and/or reproductive functions. In Solifugae , the palpi are quite leg-like and make Solifugae appear to have ten legs. The larvae of mites (and Ricinulei) have only six legs; the fourth pair appears when they moult into nymphs. However, there are also adult mites with six, or even four legs
