Two contenders are from the genus Patu: males of Patu digua described in Colombia had a body length of 0.37 millimetres (0.014 inches), while the Samoan moss spider (P. marplesi) could be as small as 0.4 millimetres (0.011 inches) long.
According to this study, there are quadrillions of spiders in the world. To clarify, a quadrillion is 1 followed by 15 zeros. Alternatively, it is a billion multiplied by a million. So there are millions of billions of spiders on earth.
The tiny maratus spiders are the size of a grain of rice.
With a burst sprint capability estimated at 16 km/h (10 mph), which is roughly half that of the fastest human sprinters, solifugids of the genus Solpuga inhabiting the arid areas of North Africa and the Middle East are the world's fastest arachnids.
The website http://www.worldometers.info/world-population/ gives the current human population as ~7.4 billion. Dividing the estimated spider population by the estimated human population yields Earth's estimated spider-to-human ratio: 2.8 million.
It is estimated that there are around 10,000 different spider species living across Australia. Australia is known for the large variety of venomous animals that live in the country and is also home to some of the most venomous spiders in the world.
Spiders don't need to eat often and can survive weeks without food. However, if insects are available, they will eat frequently. They can eat up to 4 times per day. Although they get the moisture they need from their food, they do also need water.
Probably the most well-known and most feared spider is the black widow. Most people know the black widow by its iconic red hourglass under its abdomen. They are the deadliest spider with venom 15 more times worse than that of a rattlesnake.
Australia is home to many unknown species. Researchers now say that it may be home to the world's fastest lunging predator. The karaops spider is a small and flat spider found only in Australia.
Sydney funnel-web spider. According to the Guinness World Records, the Sydney funnel-web spider, Atrax robustus, is the most dangerous spider to humans in the world. Native to Australia, this poisonous spider is found in moist habitats such as under logs or in gardens.
Why hello there, this masked peacock spider above (Maratus personatus), looking a little like The Spirit, was voted the cutest spider. Jumping spiders are also the most diverse family of spiders, with over 5,800 species in the group.
The Australian funnel-web spiders are among the deadliest spiders in the world in the effect their bites have on humans and our primate relations (although the bite has little effect on dogs and cats). There are many species of funnel-web spiders in Australia but only male Sydney Funnel-webs have caused human deaths.
The huntsman is one of the largest spiders in Western Australia — often with a leg span of up to 15 centimetres. Many people might cringe at the thought of huntsman spiders inside their homes, but WA Museum's head of terrestrial zoology Mark Harvey said the spider posed little danger to humans.
“If spiders disappeared, we would face famine,” says Platnick, who studies arachnids at New York's American Museum of Natural History, where a live spider exhibit debuted last month. “Spiders are primary controllers of insects. Without spiders, all of our crops would be consumed by those pests.”
Humans need spiders to survive. It is important to remember that spiders and other invertebrates – animals without spines – make up 98% of animal species. They are vital to the functioning of ecosystems; without them, the remaining 2% of vertebrates, including humans, could not survive.
"Arabella" and "Anita," the first spiders to spin webs in space, both died while on the United States' first space station, Skylab, in 1973. A year later, after they were returned to Earth, they were donated by NASA to the Smithsonian's National Air and Space Museum for display.
The Huntsman Spider
Low Risk and Non-toxic to humans. Non-aggressive. The name Huntsman is derived from their speed and agility when hunting prey. (Which has been known to be mice and small birds as well as other insects like cockroaches).
That is quite the sight, but picture this — millions of tiny spiders raining from the sky. While it can sound like something out of a horror movie, in Australia the transition from late summer to fall can trigger what is known to the locals as spider season.
While the theory is unproven, it is likely that spiders can detect human fear. However, there are only few studies about this topic and it is not yet known for certain. Different animals have sensory organs that are able to identify different stimuli.
The Guinness Book of World Records considers the Brazilian wandering spider the most venomous in the world. Hundreds of bites are reported annually, but a powerful anti-venom prevents deaths in most cases.
The Sydney funnel-web spider is the second most venomous spider in the world — and Australia's number one. It's extremely fast-acting venom makes it the world's most deadly spider; believed to kill in 15 minutes, it has 13 deaths recorded to it.
No spiders are known to feed directly on vertebrate blood, but Evarcha culicivora, a jumping spider (Salticidae) from East Africa, preys frequently on blood-carrying mosquitoes in the field (1). That blood is ingested is evident when viewing the spider feeding under a microscope.
Like most animals, spiders have circadian rhythms. These internal clocks tell the spider when to rest. Just like other animals, some spiders rest at night while others rest during the day.
No. Spiders typically suck the internals from their prey. Theres no juice in cheese.
