In the spider class, spiders have eight legs and four pairs of legs on each side of the body. These spiders are small arthropods belonging to the arachnid class. Most external appendages of spiders attach to the cephalothorax, including the eyes, chelicerae, other parts of the mouth, pedipals, and legs. Like other arachnids, spiders cannot chew food, so they have a short straw-shaped mouthpiece that is used to suck up the liquefied interior of their prey. abdomen. The rear body parts, including the internal organs, have the ability to expand and contract depending on the condition of the spider. Chelicerae. A pair of movable appendages in front of the spider's mouth, including its fangs. Pedipalp.
The spider's body is divided into two main parts. The first (anterior) part of the body is called the cephalothorax. Spiders are different from insects. The body of an insect is divided into three main parts: head, chest and abdomen.
What is the body part of a spider called?
The body of a spider. Spiders have two body segments. The anterior part is called the cephalothorax. The spider's eyes, mouth fangs, stomach, brain, and poisoning glands are found in this part of the body. The legs are also connected to this part. Most spiders have eight eyes, but some have fewer.
How many legs does the spider have?
The abdomen is the posterior part of the spider's two body areas. There is a spinneret at the tip of the abdomen. These are very small organs that produce silk to make spider webs. Spiders often have six of these small spinners. The spider has eight legs. This sets it apart from insects that have only six legs. The legs are usually long and hairy.
What is the outside? Spider's appendage?
Most of the spider's external appendages are attached to the cephalothorax, including the eyes, chelicerae, other parts of the mouth, pedipals, and legs. Like other arachnids, spiders cannot chew food, so they have a short straw-shaped mouthpiece that is used to suck up the liquefied interior of their prey.
What is the function of the spider's abdomen?
This allows the spider to move its abdomen in all directions, for example, to spin silk without moving its cephalothorax. This waist is actually the last part (somite) of the cephalothorax (presomites) and is lost in most other members of the arachnid (only detectable in embryos in scorpions).
