Why is it said that spiders are not insects?

Hello, here for you to find out:

Because spiders do not possess the morphological characteristics of the class Insecta. The body of the insect is divided into three segments: head, thorax and abdomen, 1 pair of antennae, 1 pair of compound eyes, 2 pairs of wings and 3 pairs of legs. The spider is divided into two parts: cephalothorax (precursor) and abdomen (posterior), no antennae, no compound eyes, no wings, 8 pairs of legs, only 8 single eyes, and one single eye.

So spiders are not considered insects and belong to the arachnids of the order Arachnids under the phylum Arthropods.

I hope I can help you and have a great day.

The reason why spiders are not insects is because spiders have four pairs of legs, and only two parts, the cephalothorax and the abdomen, do not fit the characteristics of insects

The basic characteristics of insects can be summarized as follows: the body is a three-segmented head, abdomen, thorax, two pairs of wings and three pairs of feet, a pair of antennae on the head, and the bones are wrapped around the outside of the body, and the shape is very changeable. The body of the spider is divided into two parts, cephalothorax and abdomen, and it also has 8 legs, so the spider is not an insect.

Control the temperature well, pet spiders, especially bird catchers, most of them are tropical species. Generally speaking, less than 20 degrees will reduce eating, and below 10 degrees will lead to life-threatening food. Not to mention the weather in the northeast, which is dozens of degrees below zero, it must be hopeless.

Therefore, it is indispensable to raise a pet spider with a heating pad. Of course, it's better to use an incubator if you have a piece of work. Change the coconut soil frequently, and the coconut soil is the bedding material for raising pet spiders.

In general, sterile coconut clay is used that is commercially available. However, because it is generally used after soaking, it is easier to breed mite bacteria, resulting in small white particles mixed with dots in the coconut soil, resulting in "explosion mites", which will lead to the death of spiders in severe cases. So be sure to clean it up on time.

The living habits of spidersIts silk webs can be used to snare insects and hunt insects, and can also be used as a safety bag. It often wraps leftover food in a net and saves it for the next time. Most spiders are poisonous, when preying on live prey, first bite each other with venomous fangs, let the tooth venom flow into the prey's source of noisy old body, so that the other party is paralyzed after poisoning, unconscious, and then secrete saliva that can dissolve the prey, so that it dissolves, and slowly suck the food after dissolving, until the prey is sucked clean, there is nothing left.

Although spiders and insects both belong to the phylum Arthropods, spiders belong to the class Arachnids in the phylum Arthropoda, while insects belong to the class of insects in the phylum Arthropods, and there is a significant difference in the characteristics of the two, so spiders do not belong to insects. Spiders do not have the morphological characteristics of the class Insecta. The insects are divided into three hail liter sections:

Thorax and abdomen, one pair of antennae, one pair of compound eyes, two pairs of wings, three pairs of feet. Whereas the body of a spider has only two parts, the combination of head and thorax is called cephalothorax and abdomen, and spiders have four pairs of legs, one more than insects. Therefore, spiders cannot be called insects by the standard of insects, they belong to the arachnids of the subphylum Arthropod, and are taxonomically close to the large family of insects.

Spiders are a very common type of bug in our lives, so are spiders insects or not? Let's find out.

Spiders are not insects, spiders are arthropods, and are the common name for all species of arachnids in the phylum Arthropoda, which are distributed almost all over the world except Antarctica. Spiders do not possess the basic characteristics of insects, so they are not insects.

The basic characteristics of insects are three heads, thorax and abdomen, two pairs of wings and six legs. The body of the spider is divided into two parts: cephalothorax (anterior) and abdomen (posterior), the cephalothorax is covered with dorsal armor and chest plate, there are no wings, and the cephalothorax has 6 pairs of appendages.

Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. When hunting, first paralyze the prey with the toxins in the fangs, secrete digestive juices into the prey to dissolve the prey, and then slowly suck it, without missing a clean meal.

Spiders are afraid of light and often build their webs on places that are transparent to light and wind. In addition to being used to snare prey, spider silk can also be used as a fresh-keeping bag, where the spider wraps the prey with a net of leftover food and saves it for the next time.

Spiders have a clear distinction between eating, sleeping and pulling, and domesticated spiders generally use the edge of the cage as a garbage dump where they defecate and throw away food scraps.

The above is today's sharing, I hope it can help you.

Spiders are not insects, spiders are arthropods. Because the definition of an insect is "a body with three heads, a thorax, and an abdomen, two pairs of wings and three pairs of legs, and a pair of antennae that are born on the head, and the bones are wrapped around the body, and the shape changes throughout their lives", it is obvious that spiders do not meet the characteristics of the above-mentioned insects.

In the world of insects, many insects possess incredible abilities. For example, a small flea can leap more than 200 times its height.

Even more surprising is that ants can lift objects equivalent to 52 times their own body weight. Even butterflies that look delicate can fly hundreds or tens of thousands of kilometers or even longer in a row like migratory birds. The secret to the amazing power of insects is that they have particularly well-developed musculature.

According to scientists, the muscles of insects are not only structurally specific, but also numerous.
