A Spider is any creature in the taxonomic order Araneae. Researchers place all Spiders in the taxonomic class Arachnida, which makes them “arachnids.” However, while all Spiders are arachnids, not all arachnids are Spiders. Other arachnids include mites, ticks, scorpions, and several other groups. Read on to learn about the Spider.

Description of the Spider

These creatures all share the same eight-legged body structure with a cephalothorax that contains their head and legs, and an enlarged abdomen. These arachnids also have fangs on their mouthparts that they use to inject venom. They vary greatly in coloration, pattern, and size.

Some species in this group have bodies so small that you can barely see them. The smallest species grows to just 0.015 in. long. Conversely, the largest members of this group can reach a diameter of one foot across or more!

Interesting Facts About the Spider

You can find a wide variety of traits and adaptations across the 48,000+ species in this group. Learn more about a few specific species, below.

  • Giant Huntsman – This species reaches the largest sizes in the world. Their diameter, or leg span, can measure up to a foot across! To make matters more terrifying, this species reaches speeds up to 3 ft. per second! However, their venom doesn’t pose a danger to humans.
  • Goliath Birdeater – While the giant huntsman has the longest legs, this species holds the title for heavyweight champion. It weighs up to six ounces, that’s over a quarter of a pound! Despite the name, this tarantula species does not frequently feed on birds.
  • Patu Digua – This teeny-tiny species reaches just 0.37 mm. or 0.015 in. long. That means approximately five of these creatures could comfortably fit on the head of a pin! You can find this species (if you look very carefully, that is!) in Colombia.
  • Australian Black Widow – Also known as the “redback,” this species shares a taxonomic genus with the North American black widow. Though its American cousin packs a punch with its bite, this species poses a serious danger to humans. Researchers estimate that these Spiders bite between 2,000 and 10,000 people every year in Australia.

Habitat of the Spider

Different species in this group live in a wide variety of different habitats. Some of the many types of ecosystems you can find these creatures in include woodlands, forests, wetlands, grasslands, deserts, rainforests, and more. Some live in trees and shrubbery, some live on the ground, and some even tunnel underground.

A wide variety of species also utilize regions where humans live, such as houses, farms, barns, gardens, attics, basements, foundations, and more.

Distribution of the Spider

These arachnids live virtually across the globe. In fact, you can find them on every single continent, with the exception of Antarctica. They have widespread global distribution. Some species live across vast expanses, while others utilize only a few minute regions or a single island. Each has its own unique range and distribution.

Diet of the Spider

The vast majority of species have carnivorous feeding habits, which means that they eat other animals. Most species have insectivorous diets, and eat primarily insects. However, some also feed on small animals like lizards, frogs, and even birds or small mammals. Each species has its own unique dietary preferences.

Are They Bugs?

Despite their appearance, Spiders are not bugs. Researchers place them in the taxonomic class Arachnida, while they place bugs, or insects, in the taxonomic class Insecta. You can tell arachnids from insects in that insects bear antenna on their heads, while arachnids do not.

Spider and Human Interaction

People interact with these creatures in a wide variety of fashions, often indirectly or accidentally. The immense majority of species do not pose any danger to humans. However, some species do pose a threat, and some people consider certain species as pests.

Sadly, human activity has placed some species in this group at risk of extinction. Habitat destruction and pesticide use can decimate populations and even entire ecosystems. The impact ranges from species to species.


Humans have not domesticated these creatures in any way.

Does the Spider Make a Good Pet

Some species do make good pets. However, you should never keep any wild-caught species as a pet. Captive-bred and socialized individuals of certain species can have friendly and calm dispositions.

Spider Care

Care for these creatures varies greatly depending on the species at hand. Some prefer moss or mulch substrates, while others utilize sand or dirt. The temperature and humidity vary based on what the animal typically experiences in its wild habitats. However, you can typically feed these arachnids a diet of small crickets, mealworms, and other small insects.

Behavior of the Spider

The individual behavior of these creatures varies drastically. Some species live solitary lives, only converging to reproduce. Other species live in large communal webs, or congregate in large numbers under the right conditions. Some hunt actively for prey while others lie in wait for food to come to them.

Reproduction of the Spider

The reproductive rates of these creatures vary drastically. Some perform elaborate courtship dances, and in some species the female eats the male!

In most cases, the females lay eggs, which then hatch into young. Though egg fertilization occurs internally, the males typically pass the females a “packet” of sperm, known as a spermatophore. She then uses this to fertilize her eggs.

Beliefs, Superstitions, and Phobias About the Spider

Many people villainize these misunderstood creatures. While some species can reach large sizes, and some species can pose a danger to humans, most do not harm people in any way. In fact, many species actually benefit humans. Spiders feed on a variety of different insects, many of which can damage crops or pester humans.

«Big Bud-747» is the largest tractor in the world. Photo and description

At the moment, almost every country in the worldan exhibition of agricultural machinery is held annually. One of the most iconic for Russia was the exhibition of ZAO Petersburg Tractor Plant in Moscow (2009), at which the largest domestic tractor Kirovets K-9520 was shown. But, despite its impressive size and technical characteristics, it still does not exceed the quality of its American colleague «BigBud-747», which for more than 30 years is considered the largest tractor in the world.

What are special and unique these giants?

History of production

The manufacture of this «giant» was engaged inAmerican inventor-millionaire Ron Harmon, who then closely cooperated with the design bureau «Northern Manifacturing». In fact, Ron did not expect to create a new super-tractor, which will be produced serially on the assembly line. «BigBud-747» was developed in a single copy for two brothers-agronomists Rossi, who in the 70’s were engaged in the cultivation of cotton in the city of Bakersfield, California. To date, the largest tractor in the world goes to the fields of America and for the entire period of its existence has not been put into mass production. What is the most interesting, for 37 years yet no company in the world has developed such a technique that would have similar dimensions with the «Big-Bud» dimensions and technical characteristics.

What is the largest tractor in the world capable of?

As it turned out, the power of this technology is enoughon the fact that a day to process about 400 hectares of soil. A huge 30-meter plow clung to the tractor, which is capable of plowing the earth to a depth of up to 120 centimeters. Such a productivity can not boast of any modern agricultural machinery.

Technical features of the American «BigBud-747»

Under the hood the largest tractor in the world hides a powerful 16-cylinder diesel engine with a capacity of 760 horsepower. The development of this unit involved the company»Detroit Diesel». Naturally, the appetite of such a giant was immodest. In a minute «BigBud-747» spent about 65 liters of diesel fuel. But, despite all this, the tractor was equipped with a very small fuel tank (only 567 liters). Thus, a full refueling of the tractor was sufficient for only 8-10 minutes. Aggregated tractor 6-speed gearbox. The braking system here, as well as on heavy-duty wagons, air type (on all wheels).

As for the sizes, the «BigBud-747» is simplystriking in its dimensions: the length is 8200 millimeters, the width is 6000 millimeters, the height is 4200 millimeters. The equipped weight of the tractor is 45.5 tons.

It is worth saying that tires for the «American»were developed individually by the Canadian company United Tire Company. By the way, the diameter of the tires is equal to 240 centimeters. Having received such large wheels and engine, «BigBud-747» was instantly awarded the title «The biggest tractor in the world».

What is the fate of «Big-Bud» today?

11 years after its use, in 1988year, the brothers of Rossi decided to sell this technique to the farm «Willowbrook Farms», which is located in the state of Florida. For 9 years he constantly engaged in loosening and plowing the soil. And in 1997 «Big-Bud» passed into the hands of the newowner, and now he is in his small homeland, in Montana. Having got to the new owner, it was slightly upgraded and got a new diesel engine with a capacity of 900 horsepower. According to experts, today’s cost is about 600 thousand dollars.

Until today, this tractor is in absolute working condition and is still processing and loosening the soil of fields.

Russian hero — «Kirovets To 9520»

Unlike his American counterpart, thea large tractor in Russia has a slightly less weak engine (in 516 «horses») and a more modern design. Also worth noting is a new modification of the old Kirovtsa series — K-744R3 M1, with a 428-liter engine. from.

Both models of tractors are equipped with the latestword technology, and all components are manufactured by the world’s leading manufacturers. So, the modernized «K-744R3» is equipped with a turbo-diesel engine «MB OM 457 LA» and a German axial-piston hydraulic system from the company «Bosch». According to the manufacturer, the models «K-9520» and «K-744R3 M1» have high performance, power, are characterized by ease of operation and modern appearance (see photo).

The largest tractor in Russia, the K-9520 seriesis the latest development of the Kirov plant, which inherited all the best features of its predecessors: reliable construction, a powerful and economical motor. Indeed, over the past few years the pace of development of domestic equipment has been so high that it can be confidently said that Russian tractors will be leading in the entire world market in the next 5-10 years.


So, we examined the technical characteristics of the largest tractor in the world of American origin «Big Bud-747» and the features of the new Russian «hero» Kirovets K-9520.

Largest Cockroach

Several cockroach species are considered giant. Of these, the most well known are the Madagascar hissing cockroaches and the rhinoceros cockroaches.

Madagascar hissing cockroaches (Gromphadorhina portentosa) are wingless and relatively slow moving. These nocturnal natives of Madagascar thrive on forest floors in rotting logs and feed on decaying organic matter. Hissing cockroaches grow up to over 7 cm in length from horn to antennae and can measure up to 2.5 cm wide. Unlike other species, the female hissing cockroach gives birth to live young. Males are aggressive and use their horns in combat with rival males. The hissing which characterizes this species is used in defense, mating, colony hierarchy and other communication.

Rhinoceros cockroaches(Macropanesthia rhinoceros), also known as giant burrowing cockroaches or litterbugs, are wingless, glossy, dark brown and stout-bodied. These cockroaches weigh more than 30 grams each and can exceed 8 centimeters in length. Native to Queensland, Australia, this species lives in deep burrows within the ground and consumes primarily dead leaves.

Most well-known cockroach pests measure less than 5 cm in length. American cockroaches (Periplaneta americana) are approximately 4 cm long as adults; German cockroaches (Blattella germanica) measure 1.6 cm in length as adults. Asian cockroach adults (Blattella asahinai) grow up to 1.6 cm in length, while Oriental cockroach adult females can be longer than 2.5 cm. Brown-banded cockroaches only grow to reach 1.3 cm in length, and smoky brown cockroaches grow up to 3.8 cm as adults.

Come & See the World’s Biggest Cockroach!

If you’ve ever wondered what sort of creepy crawlies are living amongst the undergrowth of the rainforest, then take a look at this impressive specimen. Far North Queensland is home to the world’s biggest cockroach.

It may not be Australia’s greatest tourism drawcard but the Giant Burrowing Cockroach, also known as the Rhinoceros Cockroach, is only found here in our tropical rainforests.

But before you all screw up your noses and cry “yuk”, this particular species of cockroach is actually considered a fantastic pet.

It’s not the kind of cockroach you find scurrying around your home looking for food scraps. This big beautiful bug lives in tropical rainforests and eats only dry and decaying leaves. Thanks to this constant recycling it plays an important role in the rainforest ecosystem.

And because it doesn’t climb or fly and is quite happy to live in a fish tank filled with soil and leaves, it is a very easy pet to own.

so what does it look like?

First of all, the Giant Burrowing Cockroach isn’t really a true bug – it is an insect.

In fact, while it is the world’s largest and heaviest cockroach, it might also be the heaviest insect in the world too. And believe it or not it is incredibly clean, contrary to a cockroach’s normal reputation. It attracts tiny mites that often live on its back to keep it clean.

This particular species of cockroach is bigger and quite different in appearance to the normal household cockroach.

The Great Burrowing Cockroach is brown, has a shiny, smooth exterior and a broad and heavy body. It can grow up to 7.5 centimetres long and can weigh up to 35g.

Surprisingly it can live for up to 10 years which is almost unheard of for insects. Especially considering the common German cockroach only lives for up to a year.

And unlike the household cockroach, the Giant Burrowing Cockroach doesn’t have wings so it can’t fly.

Throughout its lifetime, this cockroach sheds its outer non-flexible, hardened shell anywhere between 10 to 12 times before it is fully grown.

breeding and babies

Giant Burrowing Cockroaches give birth to live young and can have up to 30 babies at one time.

The female cockroach takes care of their babies in their underground burrow, which can be up to a metre deep down in the soil.

During the day the cockroaches come to the surface to forage for food and then take their dry leaves back down to their burrow.

cockroach spotting

You can only find these giant cockroaches in Australia, mainly in North Queensland and also in Western New South Wales.

And because they are known as forest floor foragers, you are most likely to come across them in the rainforest.

But you can also get a good look at these fascinating creatures at the Daintree Entomological Museum.

Okay most of the butterflies and bugs here in the museum are dead and preserved, but they are carefully labelled and displayed in glass cases.

And it’s a fascinating place to visit, even if you’re not usually a bug lover!

30 Mind Blowing Cockroach Facts

Cockroaches! Eew! We really hate those filthy insects, don’t we? Damn! They are so disgusting and of course, responsible for spreading diseases. We just hate them! However, we barely know enough about these filthy little insects which often end up infesting our homes. So, in this article on cockroach facts, let us learn 30 interesting facts about cockroaches. We are darn sure that your jaws will drop!

[wc_box color=”secondary” text_align=”left”]

Scientific name: Blattaria

Kingdom: Animalia

Phylum: Anthropoda

Subphylum: Hexapoda

Class: Insecta

Subclass: Pterygota

Infraclass: Neoptera

Superorder: Dictyoptera

Order: Blattodea.

Mind Blowing Cockroach Facts: 1-5

1. There are around 4,600 species of cockroaches. But fortunately, only 30 species share the human habitat. Out of 30 only four of them are quite famous as pests.

2. Cockroaches are highly adaptive and that is the reason why they have been living on this earth way older than us, in fact older than dinosaurs too! If new studies were to be believed, then they evolved 359 million years ago, in Carboniferous period.

3. Are you scared of cockroaches which are of roughly 1 to 2 inches? Then you better don’t see other species of cockroach because they can be as big as 3 inches. The largest cockroach is Megaloblatta longipennis which measures “just” 3.8 inches with 8-inch wingspan. It is found in Central and South America.

4. Another reason why they are so adaptable – they can survive on anything. They can eat debris, fruits, meat, other insects, our food, the list just goes on… they can eat anything just to make sure they live.

5. They are cold blooded animals. This means that they can maintain a low rate of metabolism and hence, can survive without food even for a month. But they can’t stay thirsty. Most cockroaches die of thirst and in general cockroaches can stay without water for a maximum period of about 2 weeks.

Mind Blowing Cockroach Facts: 6-10

6. Guess what? They can live for around a week without their heads. But they can hold their breath for about 40 minutes and they can remain in water for a nice 30 minutes.

7. How do the cockroaches survive without head? After the head of a cockroach is cut off, clotting will seal off the neck and prevent blood loss. The brain of a cockroach is not responsible for breathing and neither is the blood responsible for carrying oxygen throughout the body.


8. The cockroaches have something called spiracles. These are little holes in their bodies which are present in almost every segment of the body. The spiracle pipes are responsible for sending air directly to the tissues using tubes which are known as the tracheae.

9. In addition to that, they have ganglia clumps that are present within each segment of the body. These ganglia clumps are nothing but agglomerations of nerve tissues, which are very much capable of performing the basic nervous functions which control the reflexes.

10. So, a cockroach can survive decapitation. However, it will eventually die off because of thirst and hunger (thirst will kill it first because they can’t stay thirsty for a very long time).

Mind Blowing Cockroach Facts: 11-20

11. These little creepy animals are fast runners by birth. Yes, not just the adults but the ones which are born run 3 miles per hour. Their hind limbs can move 27 times per second when they are running and just not that the spines on their legs allow them to maintain their speed on the walls without slipping.

12. The most common types of cockroaches are German cockroach, American cockroach, Australian cockroach and Oriental cockroach.

13. It takes just 123 days for a baby German cockroach to grow into an adult.

14. An American cockroach is attracted to alcohol! They are mostly attracted to the alcohol which has hops and sugar in it. They love beer! Now these tiny creatures are after what we love too.

15. Though most of us hate that 6-legged creepy insect, there are people who love eating cockroaches! In China, they are roasted or deep fried and are sold on sticks (like kebabs) on the streets. There are other tribes as well who eat cockroaches. Though they are considered healthy, doctors warn against this practice of including cockroaches in diet.

Mind Blowing Cockroach Facts: 16-20

16. If there is anything which cockroaches can’t take is the cold. Yes, as mentioned they are cold blooded animals so their temperature depends on the temperature of the surroundings. If the surroundings are too cold, then there are less chances for a cockroach to survive. But there is one species of cockroach called Japanese cockroach (Periplaneta japonica) which can survive a whopping -8 degrees Celsius. It hibernates. Even if it freezes it can unfreeze itself when the temperature return to normal. They are the only ones to walk on ice.

17. Did you know there is something called leaproach? No, it is not a hybrid but it is a new species of cockroach which was found in the Table Mountain in South Africa in 2009. Why did they name it as leaproach then? It is because this cockroach jumps. Feel lucky that these hopping cockroaches are not in your home. Its scientific name is Saltoblatella montistabularis.

18. Cockroaches are thigmotropic i.e., they like to be touched on all sides! They like to be in contact with something solid from all sides of the body. Now did you understand why cockroaches are in love with those crevices of your home?

19. Just like dogs, cockroaches can be conditioned. Makoto Mizunami and his colleague Hidehiro Wantanabe of Tohoku University found that cockroaches can be conditioned just like dogs. Before a nice sugary treat, cockroaches were introduced to vanilla or peppermint scent. After few days, cockroaches drooled by smelling the scent.

20. It is a myth that cockroaches survive nuclear explosion. But they can bear more radiation than us. While an average human can tolerate 800 rems (unit of radiation dose), the cockroaches can tolerate up to 10,500 rems.

Mind Blowing Cockroach Facts: 21-25

21. Cockroaches are not early birds! They can’t remember things and cannot even learn new memories during the mornings. Researchers tested this by trying to teach them to genuinely prefer bad odor. While they succeeded when they were taught during midday or night or during sunset time but roaches failed miserably when they were taught during the daylights.

22. Did you know that even cockroaches fart? They fart around 35 gm of methane a year which is 43 times heavier than themselves!

23. There are higher chances that you had eaten a cockroach or at least parts of it in your lifetime. We say this because even the delicious chocolate bar, cheese, peanut butter, popcorn etc. will have portions of this insect and we relish eating them!

24. There is one variety of cockroach – the Madagascar hissing cockroach, which speaks with the help of its air passageways. These passageways work more or less like the vocal cords of humans.

25. Cockroaches are social animals. Though you would not see them moving in groups but they do sometimes select a place where many roaches hang out together. German cockroaches secrete aggregation pheromone which attracts other roaches.

Mind Blowing Cockroach Facts: 26-30

26. They are always blamed for spreading diseases and doing harm to humans but they do good work for earth. They help in decomposing the debris thereby help bringing the much-needed nutrients back to the soil. They also serve as food for other small animals like lizards, birds and in this way, keep the food chain in good shape.

27. Cockroaches helped our ancestors. How, you ask? The tiny creatures used to feed on the bat’s dung from cave’s walls and ceilings and made the caves neat where humans could dwell.

28. There is one cockroach everyone would be amused to see. That is Luchihormetica luckae. The specialty of this cockroach is that it glows! It is bioluminescent and it is toxic and looks similar to a bioluminescent click beetle (markings on the body). The bioluminescence property is used as a defensive mechanism by the cockroach which is very rare in the animal world.

29. Scientists are now trying (even succeeded a little) to turn cockroaches into cyborgs. They are gluing receiver on to the cockroach’s back and inserting electrodes in the insect’s antennae. This way they are able to control its movements.

30. China is not famous for eating cockroaches alone but equally famous for its cockroach farms. They rear cockroaches and guess what? It is a booming industry there now and it has helped improving the economy of the country as well!
