Tarantula is a term for a type of profit that is large, it turns out not to belong to the species of insects. in the world has been discovered spider monkey is a New World monkey that belongs to the genus Ateles, part of the sub-family Atelinae, an endangered family of Atelidae. find out more about the weight of average spider: fact, size, and identification.
What is an insect spider?
At first glance, spiders do have similarities to insects, but in fact, spiders belong to a class called Arachnids. While pests belong to another course, specifically Insecta.
Arachnids, such as spiders, scorpions, and mites, have only 2 segments of the body. Another case with insects that have 3 segments of the body. Another distinction is that Arachnids have 4 pairs of legs, while bugs have 3 pairs. Well, so don’t mistake spiders for insects anymore.
How do spiders make their webs?
The spider begins to make webs from the glands on its tail. he began by throwing a few lines of their silk thread towards the direction of the wind. Some of these nets will become longer, the wind takes them to nearby objects such as twigs and tree branches.
How to eat profit?
Spiders are mostly carnivorous and feed on small animals such as insects such as mosquitoes, flies, ants, and grasshoppers caught in their webs. Spiders have 4 pairs of legs (8 pieces).
Why shouldn’t spiders be killed?
You better not kill spiders. Because basically, spiders are not dangerous animals. Precisely they are very useful for preying on pests that carry diseases at home.
Are large spiders dangerous?
Spiders are one of the types of animals that many people fear because of their creepy and bite-able shape. However, did you know, spider bites are usually harmless. Of the thousands of spider species present in the United States, most are harmless.
What is the smallest kind of profit?
The Colombian spider Patu Digua has a size of only about 0.059 cm. Not only is it named the smallest spider in the world, but it is also the rarest species of spider.
What’s the biggest profit?
The largest known spider in the world is the male goliath-eating spider (Theraphosa Blondi) collected by expedition member Pablo San Martin in Rio Cavro, Venezuela in April 1965. It has a foot span record of 28 cm (11 in) – enough to cover a dinner plate.
How many legs in spiders?
Spiders are a sort of bookworm (arthropod) with 2 sections of the human body, four pairs of legs, wingless, and don’t have any stained mouth.
Weight of average spider
According to the study, the weight of average profit reaches 0.05 – 170 g.
In addition to the weight of profit, you should also know the Weight of the Average Irukandji Jellyfish. Have you seen iracongi pictures? iracongi is an Irukandji jellyfish, the smallest marine species that has a very dangerous sting and can cause deaths.
Has a very strong net
One of the characteristic features of spiders is of course the webs that they can remove to build nests. There are different types of spiders in the world, and the strength of their webs varies. But in general, cobwebs have tremendous power.
When compared to an iron wire, cobwebs of the same thickness have 5 times the strength. Even if a cobweb can be enlarged to as thick as a pencil rod, it can stop a Boeing 747 from flying! Wow, that’s amazing!
Able to jump very far
If spiders can participate in long jump races against humans, they will certainly be the winners. Spiders can jump around 40 times the amount of the bodies. It’s the same as someone with a height of 175 cm who can jump 7 km at a time!
Uniquely, spider legs do not have strong muscles. They Leap by contracting the abdominal muscles till fluid is pumped to the hind legs. Then their hind legs are straightened back, and that’s what makes their bodies bounce so far.
Despite its terrible look, spiders don’t have teeth. Some species of spiders have a pair of pseudo fangs that are not used to chew their food, but only to inject poison into the body of their prey.
After the prey dies, the spider will secrete an enzyme liquid that will soften the body of its prey. He then simply devours his victim by sucking on it.
Not all spiders make webs even though they can
All spiders can produce webs that serve to catch prey, but not all spiders want to do so.
Spiders are like tarantulas for example. Unlike other types of spiders, tarantulas never bother to build traps for prey.
Instead of working hard to make large nets, tarantulas prefer to crawl around and climb trees to catch prey and eat them on the spot.
Not only white, but spiders can also produce gold webs
Most of the cobwebs we encounter are usually white. But did you know that there is one type of spider that can produce gold-colored webs?
They are Nephila spiders. Unlike other spiders, Nephila-type spiders have gold-colored webs that will look very beautiful when exposed to sunlight.
And similar to the Caerostris Darwini cobwebs, Nephila’s golden webs are also strong and even very durable because they can last for years.
Not only on land but spiders also make webs underwater
While all kinds of spiders live on land, a spider named Argyroneta Aquatica spends most of its life in the water.
To be able to breathe in the water, this spider makes a bell-shaped web that can capture oxygen around it and allows this spider to breathe in the water.
In addition to breathing, this bell is also a house where Argyroneta Aquatica spiders can breathe, prey, mate, as well as lay eggs, and raise their offspring.
Spiders are widespread on the face of the earth. There are about 45 thousand species of spiders that we can find all over the world, except in the Antarctic Continent. A common feature of spiders is that they have four pairs of eyes, eight legs, are wingless nor have chewing mouths, as well as carnivores.
The typical physical characteristic of a spider is that it has two segments of the body. The front body is called cephalothorax or prosoma which is a combination of head and chest. While the back is abdominal (abdomen) or opisthosoma. The link between the cephalothorax and abdomen is a thin membrane called pedicels.
Generally, spiders do not have good vision, aka can not distinguish colors. It is only sensitive to dark and light. To mark the presence of their prey, spiders rely on vibrations present in their silk webs. Or in the land, the water, and the place he inhabits.
The classification of Spiders consists of several classes. To date, about 40,000 species of spiders have been studied and classified into 111 tribes. However, given that these animals are so diverse, many of them very small in stature, often hidden in nature, and even many specimens in museums that have not been well described, it is believed that the possibility of a variety of spider species can all reach 200,000 species.
Some descriptions of the spider family:
Family Atypidae (Nest-bag spider)
These spiders make silk webs at the base of tree trunks, nets sticking out from a little place in the ground to about 150 mm above the ground. When an insect lands on top of this web, the spider bites through the web, grab the insect, and pulls it into the web. This spider is 10-30 mm long.
Family Araneidae (Circle-shaped nest spinner)
It is a large and very widespread group and almost all of its members make a circle-shaped cobweb. There is considerable diversity in size, color, and shape in this family.
Family Tetragnathidae (Long circle-shaped nest spinner)
These spiders have very long and sticking chelicera, especially male ones. Most types are brownish and relatively long and slender, the legs, especially the front pair, are very long. These spiders are usually found in marshy areas.
Family Agelenidae (Funnel-shaped nest-making spider)
These spiders are a large group (approximately 250 species in North America) of common spiders that make spider nests like sheets in the grass, under corals or boards, and in ruins. Nests of a larger type are somewhat funnel-shaped with one reed-shaped hiding place pointing down into the material where the nest is made.
Family Hahniidae (Hahniid nest-leaf spider)
Hahniid-hahniid is a small spider, 1.5-3.2 mm long, with a thread-making tool in a single transverse line. They make a spider’s nest similar to Agelenidae, without hiding places like funnels. The spider’s nest is very delicate and rarely seen except covered by dew (Borror, 1996).
The order of the spider is further divided into three major groups on the suborder level, namely:
- Mesothelae, which is a primitive, non-venomous spider, with clearly visible segments of the body; showing a closer kinship with his ancestors, namely arthropods.
- Mygalomorphae or Orthognatha is a group of spiders that make burrows, and also that make trap holes in the ground. Many of its types are large, such as tarantulas.
- Araneomorphae is a group of ‘modern’ spiders. Most spiders we encounter belong to this suborder, given that its members are made up of 95 tribes and cover approximately 94% of the number of spider species. The fangs of this group point slightly forward (and not upright as in the tarantula group) and are moving in the opposite direction like a claw biting its prey.
