No, spider web is not made of poop. Poop is the waste remaining from digested food. Spiders expel it from the anus just like you do, as part of their digestive process. Silk is made with proteins in the silk glands and is excreted through the spinnerets.
In fact, house spiders can be helpful.
"If left alone, spiders will consume most of the insects in your home, providing effective home pest control." And by keeping these populations in check, spiders can even help limit the spread of disease carried by insects like fleas, mosquitoes and cockroaches.They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.
Males don't possess a penis in the traditional sense. Instead their anatomy includes a pair of appendages called pedipalps, which are much larger in males and have syringe-like enlarged ends. Once a male spider finds a receptive female, he deposits sperm on a sperm web before charging his pedipalps with it.
Spiders aren't social, so they don't need the range of emotions that, for example, humans and dogs do. We can't ask spiders how they feel, but I'm sure that they have simple and basic emotions. They can certainly get scared and stressed, and possibly feel happy and satisfied when they have caught food.
Yes. Spiders have an open, blood circulatory system. The heart is tubular with a single cavity and with valves to maintain the flow of blood always in the same direction. The spider's blood is pale blue due to the presence of haemocyanin dissolved in the lymph.
Spiders technically do not have brains, just because of the way "brain" is defined by people who study anatomy. But they do have concentrations of neural cells that fill up most of the space in the cephalothorax. Jumping spiders, and maybe some others, have "brains" that extend down into the legs.
Eunuch spiders still have balls. THE male Malabar spider may lose its genitals, but no one can accuse it of needing to grow a pair. Even after its reproductive organs snap off, the spider is still willing to take down rivals. Genital loss is known to make Nephilengys malabarensis a more aggressive fighter.
Your spider most likely does not remember what you did, since most of its nervous system's structure is so basic.
Spiders see us as furniture that moves. They have no interest in us. They are not curious about us. They are in your room because they are looking for bugs to eat.
Spiders don't watch you sleep, or eat or sit or play on your phone. They don't see you simply because they have pretty bad eyesight. Most spiders can see about an inch or two in front of them.
No, likely not. Some spiders can see in great detail, far greater than ours but it is rare and even then memory of complex structures (moving, fluid, etc) is hard for us let alone spiders with far smaller brains and somewhat more basic insticts.
What is the average lifespan of a house spider?
Goliath birdeater: 15 – 25 years
Brown recluse spider: 1 – 2 years
Southern black widow: 1 – 3 years
Spiders don't produce urine like we do, but produce uric acid, which doesn't dissolve in water and is a near-solid. In this sense, spiders don't deposit separate feces and urine, but rather a combined waste product that exits from the same opening (anus).
Most spiders have terrible eyesight. They sense their world mostly through vibrations and scent/taste. They can see movement and objects much more clearly than can other spiders. They will follow your movements, including your head movements while you are looking at them.
Spiders very rarely bite humans. First of all, spiders are predators, and human beings are never a source of food for spiders as they are far too large. Regardless of rumours you may hear, spiders do not chase humans in an attempt to bite, eat or kill them. Spiders for the most part will stay well clear of humans.
Spiders cannot lay eggs or live inside any part of the body. Spiders generally avoid humans as much as they can, but some species will bite if disturbed; a spider bite is a serious injury and should be treated as such. hominis, which lays its eggs in human skin.
The spider's sex does not change throughout its lifetime.
Both the male and female reproductive organs are at the rear of the abdomen, but spiders don't mate by coupling these organs. Instead, the male deposits some sperm onto a small web and picks it up on the end of his pedipalps. When the female is in position, the male deposits the sperm in the female's genital opening.
Many spiders lay their eggs inside a silk egg sac, which is usually hidden in a web, affixed to a surface, or carried by the female. Spiders may produce multiple egg sacs, each containing up to several hundred eggs.
Male spiders have longer legs, which is most likely an evolutionary characteristic as they roam farther and more frequently than females. Female spiders don't leave their webs, whereas male spiders go out hunting.
Mating doesn't require male and female sperm and egg to match. There are also species of Spiders where the females will die soon after she lays the eggs. Others carry them with her and they will start to emerge but when they so she will die.

Most species do not die after they lay eggs. Some spiders lay several egg-sacs full of eggs during the late summer or fall, and then when cold weather comes they probably die. Some female spiders sacrifice themselves to their babies who eat the dying mother as they emerge from their egg sac.
Like Charlotte in CHARLOTTE'S WEB, many spiders die in autumn after producing an egg sac. But some adults live through the winter, mate in the spring, and then die, and some survive for two or more years. Most baby spiders hatch when the weather gets warm, but a few hatch from their eggs during fall or winter.
Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
Spiders typically have eight walking legs (insects have six). They do not have antennae; the pair of appendages in front of the legs are the pedipalps (or just palps). Spiders' legs are made up of seven segments. Starting from the body end, these are the coxa, trochanter, femur, patella, tibia, metatarsus and tarsus.
Contrary to urban myth, spiders don't commonly crawl into people's mouths while they're sleeping. They prefer to avoid humans. When spiders sleep or hibernate, they're most likely to be in their webs, in protected places such as cracks in walls or, among species that burrow, in tunnels.
To extend their legs, spiders rapidly increase pressure in their cephalothorax -- the round, bulb-like midsection to which all the legs are connected. This increase in pressure sends hemolymph (blood) flowing to the extremities, causing the legs to stretch outward.
Because spiders mostly have one set of muscles for moving their legs, the ones that contract. The muscles that extend the legs are “missing” and leg extension is accomplished with blood pressure. When a spider dies the contracting muscles pull the legs in.
Well, the spider ends up losing a lot more blood before they're able to eject the leg. Since extension of the leg is caused by an increase in blood pressure to the limb, the death curl is what happens when the spider's blood pressure gets too low for it to extend the limbs.
Spiders don't use muscles to extend their legs, they only use muscles to flex them. SO, the more pressure forced on the legs, the faster they can be extended. The faster its heart beats, the more pressure is forced into the legs, the faster they can extend.
Scorpions got even bigger. When we run quickly, our breathing speeds up to get more oxygen into our systems. Spiders, however, have a passive respiratory system. This means, when spiders exert themselves, “they have to stop and let the oxygen pass over [their lungs].
