Spiders breathe in a very different way from you. Instead of lungs that draw air in and out with a chest pump, spiders use special openings and internal structures that move oxygen through their bodies by gas exchange. Spiders use book lungs, tracheae, or both to bring in oxygen and release carbon dioxide. Because spiders…
Spiders do sleep, even if their sleep looks very different from yours. When you ask how do spiders sleep, the short answer is that they enter a quiet, low-energy state with less movement, slower body activity, and weaker responses to touch or vibration. Science confirms that spider sleep is real, but it is harder to…
Spiders mate through a careful process of courtship, sperm transfer, and egg production. If you want to know how spiders mate, the male and female must first recognize each other. The male uses special body parts to move sperm into the female’s body, where she can store it until eggs are ready to be fertilized….
Australia has a huge variety of spiders. The simple answer to how many spiders are in Australia is: a lot, and more than scientists can count with full certainty.

If you are wondering how many spiders are in a house, the short answer is that it can be anywhere from a few to several dozen in a typical home. Larger or older houses may have more. Most of the time, a small spider presence is normal. It often means your home has a few…
Spiders are one of the most common animal groups on Earth. The answer to how much spiders are there depends on whether you mean species, individuals, or total biomass. Scientists have recorded more than 53,000 spider species so far. The true number is likely higher because many species still have not been named. Spiders live…
Spiders do not all live for the same amount of time. The answer to how long spiders live depends on the species, sex, and life stage. Many small spiders live for about a year. Some larger species, especially females, can live for several years. The biggest clue is this: an adult spider often lives much…
Spiders can live without food for much longer than most people expect. Many common spiders survive for several weeks without eating, and some larger species last one to two months, especially if they have water. That range depends on the spider’s species, size, age, activity level, and environment. A quiet spider in a cool, damp…
Jumping spider molt timing depends on age, size, and health, but most molts follow a similar pattern: a pre-molt pause, a short shed, then several days of recovery. If you know how long each phase usually takes, you can avoid feeding too soon and reduce stress for your spider. During molting in jumping spiders, the…
Spiders are everywhere. You can find them in your backyard, forests, farms, and even your home. When you ask how many spiders are in the world, the short answer is that the number is enormous. Scientists think the global total likely reaches trillions, and some estimates go as high as quadrillions of individual spiders. That…
