    Spiders have eight legs.

    The spider is surrounded by a chitin exoskeleton, and the body is clearly divided into cephalothorax and abdomen, which are often connected by a thin stalk that becomes the first abdominal segment of the abdomen, and has no caudal segment or tail whip. The spider has no compound eyes, and the cephalothorax has 6 pairs of appendages.

    The first and second pairs belong to the head appendages, of which the first pair is chelicera, most of which are chelicera, most of the base is chelicera, the tip of the end is chelicera, the teeth are tubular, and the chelicera or cephalothorax is poisonous, and the venom secreted by it is derived.

    The second pair of appendages are called foot whiskers, shaped like footsteps, but only have 6 segments, the basal segment near the mouth forms a jaw-like protrusion, which can help feeding, and there is no major change in the female spider's terminal segments, while the male spider's foot whiskers are specialized as reproductive auxiliary organs, with sperm storage and sperm transmission structure, called tentacles. The third to sixth pairs of appendages are footed, consisting of 7 segments, with claws at the end and a tuft of bristles under the claws, so they are suitable for crawling on smooth objects.

    Habits

    Because spiders are highly sensitive to changes in environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor habitat and biodiversity changes, and their species composition and population changes have become important indicators for environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

    Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them. Crab spiders wait for their prey on flowers that are similar to their body color. Li Wu.

    Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole. funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself resides in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

    Spiders have eight legs (four pairs of feet) and the eight legs you mentioned.

    Spider is a generic name for all species of the phylum Arthropoda, Arachnida, and Araniae.

    The spider has 4 pairs of feet, which are divided into basal segments, rotating segments, leg segments, knee segments, tibial segments, posterior tarsal segments, tarsal segments, and tarsal terminal segments (upper claws). The feet are covered with bristles and have several sensory organs, such as elongated bristles (which sense air currents and vibrations). After self-cutting, it can be regenerated the next time it molts.

    Insects are 3 pairs of legs. Insects are a general term for the class Insects of the phylum Arthropod.

Suppose all 100 chickens are chickens, then the total number of feet is 2 100 = 200 (chickens) The number of rabbit feet is 0, and there are 200 more chicken feet than rabbit feet, when in fact there are 16 fewer chicken feet than rabbit feet. Therefore, the difference between chicken feet and rabbit feet is more than known (200 + 16) = 216 (only), because the rabbit in it is replaced by a chicken.

The reasons for this phenomenon vary according to various theories, but it is believed that the mechanism that induces finger development is problematic between the sixth and eighth weeks of the embryo. Usually when no other deformities are found during the physical examination, we call it isolated polydactyly, which is usually a dominant form of inheritance, so if this mother finds that your child belongs to this type of inheritance, she may wish to go to her mother's or husband's family to see if there is this type of disease. >>>More
