What is the life cycle of spiders
Spider:
The spider falls under the phylum Invertebrate
Arthropods, and belongs to the family of spiders (Araneae), along with
scorpions, tarantulas, a large number of mites, and ticks that form the class
Arachnida.
The spider differs from other arachnids in that
it has eight legs instead of six.
The spider's body is also divided into two main
parts: the front of the head and the abdomen, while the bodies of other
arachnids are divided into three parts.

What is the life cycle of spiders |
Where does the spider live:
The spider can live anywhere there is sufficient
food for it, on all continents.
Spiders can be found in fields, forests, swamps, dry desert environments, and inside caves.
There is a type of spider that lives most of its
life underwater, and we find another type that lives next to the top of Mount
Everest, the highest mountain in the world.
Other types of it live inside homes, warehouses,
and abandoned buildings, and other types live on the walls of
buildings, on ceilings, and on windows.
And doors.

Order of the main spiders:
The number of spiders found around the world
includes more than 40,000 species, classified into approximately 110 families.
Spiders are divided into three main orders:
Tarantula-shaped spiders:
Its scientific name: Orthognatha.
The following families live in warm climate
areas, and the following families fall under this suborder: The following
families descend under this suborder: (Theraphosidae), (Dipluridae),
(Ctenizidae), (Hexathelidae), (Atypidae).

Spiders with forceps:
Its scientific name: Labidognatha.
The
following families fall under it:
The jumping spider family (Salticidae), the
Linyphiidae family, the Araneidae family, the Lycosidae family, and the
Theridiidae family.

Fragmented spiders:
This suborder includes only one family called

Spider body composition and characteristics:
The spider has many shapes.
The spider may be short or long, fat or thin,
with short and thick legs or long and thin.
Most spiders have a brown, gray or black color.
Spiders do not have bones, but are equipped with
hard skin that acts as an exoskeleton, and the spider's body covers the hair
and spines.
The spider's body is divided into two parts: the
prosoma or the front of the head (Cephalothorax) and the abdomen
(Abdomen).There is a small node in the middle that connects the two parts
together, known as the pedicel.
Prosoma or fusion of the front of the head and
chest:
The upper and lower parts of the prosoma are
covered with strong structures to protect them.
The upper part is covered with a corneal shield
(Carapace), the lower part is covered with a sternum, and the lower appendages
are known as the labium.
Prosoma contains the eyes, mouth and legs of a
spider.

Spider's eye:
Most spiders have six to eight eyes, and their
eyes are simple because they do not have compound lenses like those of insects,
and some spiders can only distinguish the difference between light and shadow.
We find that there are a small number of spiders
that have good eyesight, but most types of spiders depend on seeing, searching
for their prey, hunting, and wandering, and their predators avoid touching,
feeling shaken, and tasting.

Spider mouth:
The mouth area consists of two jaws containing
canines known as chelicerae, which the spider uses to stabilize the prey while
inserting poison into it, in addition to an upper plate (The labrum) and a
lower plate (The labium), which form the upper and lower parts of the mouth.
It also contains A row for cutting food in the upper jaw.
The spider feeds on many living organisms, such
as insects, small birds, frogs, reptiles, etc.
It also has the ability to sense and see the
movement of prey and distinguish between different prey.

Belly:
The spider's abdomen is covered by a thin,
flexible membrane that can expand during food intake and egg development.
During silk spinning and mating, the abdominal
part moves with the help of the septum that separates it from the prosoma part.
From the outside, the abdominal area consists of
a covering known as the scribal lung covering, which protects the internal
organs sensitive to the spider.
It also contains the opening of the reproductive organs and the spindles responsible for producing silk threads.
The inner abdominal area contains most of its
important internal organs, such as the reproductive system, lungs, and digestive
system.
Reproduction process and life cycle of spiders:
The process of reproduction is the basis of the
spider's life, and spiders reproduce indirectly through sexual reproduction and
internal fertilization, as sperm are not introduced into the body of the female
spider by the male's reproductive organs, but this is done through an
intermediate stage.
Male spiders place sperm inside their own
network of silk threads, pulling them to the foot tentacles to insert them into
the openings of the female’s reproductive organs, whose role begins to store
them inside them, to choose sperm capable and suitable for fertilizing eggs.
Spiders complete their life cycle after laying
approximately 1,000 to 3,000 fertilized eggs in a silk bag after mating to keep
the eggs at a constant level of humidity.
What is the life cycle of spiders
All spiders, from smaller jumping spiders to
larger tarantula spiders, have the same general life cycle.
Spiders are known to mature in three stages: the
egg stage, the young spider stage, and the adult stage.
Although the details of each stage differ from
one type to another of spiders, However, all stages are very similar، Mating rituals for spiders also differ, and male spiders must approach
the female carefully or he may make a mistake to become prey.
Even after mating, many male spiders die, even
though the females are completely independent and will take care of their eggs
on their own.
Despite rumors, the majority of female spiders
do not eat Her husbands.

Eggs, the embryonic stage in the life cycle of spiders :
Spiders
After the spiders mate, female spiders store
sperm until they are ready to produce eggs.
The mother spiders first build an egg sac of
silk strong enough to protect their developing offspring from environmental
elements.
Then the females deposit their eggs inside them
and fertilize them as soon as they appear.
One egg sac may contain A small number of eggs
or several hundred depending on the species of spiders.
Spider eggs usually take a few weeks to hatch,
and some spiders in temperate regions will emerge from the egg sac and appear
in the spring.
In many species of spiders, the mother guards
the egg sac from predators until the young hatch, and other species will place
the sac in a safe place and leave the eggs to their fate.

Mothers of wolf spiders carry the egg sac with
them, and when the eggs of these spiders are ready to hatch, females will bite
the sac to open it and free the spiders, and the strange and unique behavior of
this species, the young spend up to ten days
hanging on their mothers' backs.
Young spiders, stage of immature spiders :
Spiders
Young immature spiders resemble their parents
but are much smaller when they first hatch from the egg sac.
These young immediately disperse, some by
walking and others by a behavior called ballooning or swell.
Young spiders that disperse will collide by
swell on a twig or other transverse body and inflate their abdomen, as they
release threads.
Silk from their spindle, letting the silk hold
on to the wind and carrying them away, and while most young spiders travel
short distances in this way، However, some of them can be carried at
significant heights and over long distances.
Young spiders will molt repeatedly due to their
increasing size and be very weak until a completely new exoskeleton is formed.
Most species reach adulthood after 5 to 10
moults.
In some species, male spiders will be fully
mature when they emerge from the sac, and female spiders are always larger than
Males, so they often take longer to mature.

Puberty, sexually mature spiders :
Spiders
When spiders reach adulthood, they are ready to
mate and start the life cycle again.
In general, female spiders live longer than
males, and males often die after mating.
Spiders usually live from one to two years,
although this varies depending on the species.
Tarantulas have an unusually long life, and some
female tarantula spiders live 20 years or more.
Tarantula spiders also continue to moult after
reaching adulthood, and if female tarantulas moult after mating, they will need
to mate again, because they get rid of the structure.
