These fun facts will educate you, regardless of whether you're a fan or skeptical about spiders. The ecosystems of the globe are dominated by spiders, which are tiny but powerful. Their habitats are decreasing, and they are becoming more endangered. The truth is that spiders can be just as valuable to the planet as large animals.
Spiders are arachnids. They have eight legs. Two are specialized to do a variety different functions. They have a straw-shaped mouth, which sucks up liquids. The smallest spider can only measure one-fifthof a meter long. Spider silk, which is five-times stronger than steel, can also be produced. They spin intricate webs in order to catch other insects. Vitamin K is found in silk, which reduces bleeding.
Spiders have a complex courtship ritual that includes a lot of dancing and gestures. They can also balloon together in certain weather conditions. A spider web they can create can also stop an airplane from moving. However, the main purpose of a spider's life is to catch and consume its prey. This is possible because of their amazing hearing and smell. They have superpowers senses, which allow them to detect vibrations from other creatures. They can also detect light. They can even jump up on walls to lure their preys to drink their liquids.
Spiders are also smart. They use complex systems of sight, hearing and smell to communicate with their prey. They also use vibrations in order to measure how far they are from the prey.
The Phidippus audax spider is a good example of this. It uses a set of hairs to detect particle movement. The spider can also hear from as far as 10 feet away.
Another great example is The Peacock-spider. This spider woos its potential mate with a fan-shaped extension. It is also among the smallest spiders on the planet. It is only about a quarter of a centimeter long. It also has the first spiderweb in the world.
Spiders can survive for as much as 45 years. A spider can consume 10 percent of its bodyweight in food each day. The largest spiders can grow to the size of a dinner plate. They can even capture large animals. They're not alone in this feat. Some have eaten bats. Some have poisonous veins. Despite their frightening name, spiders can be quite harmless for humans. The American House Spider (or American House Spider) is the most frequent house spider in North America. Its fangs are too small to bite, but they are strong enough to hold onto smooth surfaces.
Another thing that is fun about spiders are their mouths. This secondary set of eyes allows spiders to sense light and determine distance. This is how they create spider webs. However, even the smallest spider can fit on a pin's head.

How does your brain control your body's functions?
To ensure that they work together, messages are sent by the brain to other organs. Everything in your body is controlled and managed by your brain. It tells your stomach to digest food and your lungs to breathe air; it tells your arms and legs to move.
Your brain is made of billions, or neurons, of nerve cells. Neurons communicate by sending electrical signals, called action potentials, on axons. Each neuron is covered by a cell membrane. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. Ion movement is what causes the neurons to fire.
When a neuron fires, chemicals called neurotransmitters are released into the space between the neuron and the next neuron. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. This causes the second neuron to fire too.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. The impulse travels along an synapse between the neurons. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
They are vital for the communication between nerve cells. They also coordinate activity between different brain parts.
Which is the most mysterious spot on Earth?
Antarctica is one of the most mysterious places on Earth.
What is it that makes this place so interesting? Because it is unlike anything else on Earth.
It is remote and difficult to reach. This site has more to it than meets your eye.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica, The South Pole
It is not known why Antarctica was called Antarctica. Some believe it means "land of ice." Others think it comes from Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to some legends, one of these twins was born in winter. Thus, the term antarctic.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would translate to land that is turned away from the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the driest, windiest of all continents. Because it is too frigid, there are no trees, animals, or plants.
And yet, this frozen wasteland is teeming with life.
It houses approximately 90% of all Earth's living organisms. Here are approximately 50% of all the animal and plant species in the world.
What makes Antarctica so special? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large amounts of ice to float above ground.
These glaciers are responsible for covering 80% of the continent. They are growing in size every year.
The Antarctic ice sheet has grown 60ft since 1960.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead worldwide flooding.
But not everyone thinks this is bad news. Global warming may be beneficial for some scientists. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
