Spider

What kind of animal is a spider?

Spiders are an order of predatory, invertebrate animals of the class arachnids; The body has only two parts, eight legs, a mouth without chewing jaws, no wings - the same class of Arachnids as scorpions, ticks….

All spiders have the ability to make cobwebs, a thin but strong silk-like fiber of protein, secreted from the back of the abdomen. Spider webs are used for many things such as creating ropes for climbing walls, nesting in rock cavities, creating places to hold and pack bait, holding eggs, and holding sperm.

Many spiders use the sticky nature of their webs to trap prey, while others hunt by stalking and ambushing.

Aside from the 150 species of spiders in the families Uloboridae, Holarchaeidae, and Mesothelae, all other species are capable of injecting venom when biting – either in self-defense or to kill prey. However, only 200 species have venom that is harmful to humans. Many types of spiders are large, painful bites but do not cause toxicity or death.

Chest part

Spiders have four pairs of legs on either side of the cephalothorax. There are sparse hairs on the body and legs to feel vibrations and sounds and scents.

Most insects live in terrestrial environments. The body of an insect consists of three segments: head, thorax, and abdomen. The head consists of a pair of compound eyes and a pair of antennae. Usually, two pairs of wings are connected to the thorax. Three pairs of legs are connected to the chest.

Insects undergo complete metamorphosis. The four stages of the life cycle are egg, larva/pupa, pupa, and adult. The three types of insect feeding mechanisms are chewing, sucking, and sponges. Chewing oral insects such as mandarin, maxilla, and labium. Insect suckers are called true bugs. Sponge insects secrete saliva on solid food, and the solution is sucked up by the mouth.
