Spiders: This is a cluster of arthropods of the arachnid subphylum. They are characterized by a body divided into two main parts (cephalothorax and abdomen) and having eight legs. Spiders are predators, and many species use webs to catch their prey. They are spread throughout the world and play a key role in ecosystems as controllers of insect populations. Many species of spiders produce venom that is dangerous to their prey, but only a few are dangerous to humans.

Information
- Classification: Spiders belong to the class Arachnida, which also includes scorpions, ticks and mites.
- Body structure: The typical structure of a spider includes a cephalothorax with eyes, maxillae (with venom glands) and legs, and an abdomen.
- Number of legs: All spiders have eight legs, which distinguishes them from insects, which have six legs.
- Cobwebs: Not all spiders form webs. Those that do form them mainly use them to catch prey, but also as shelter or even to travel on the wind in a process called "ballooning."
- Diet: Spiders are predators and feed mainly on insects. Some larger species may prey on small vertebrates such as lizards and birds.
- Reproduction: Females lay their eggs in cocoons, which they often protect or carry with them. Many species of spiders practice complex mating behavior.
- Venom: Most spiders have venom with which they paralyze or kill their victims. However, only a few species have venom strong enough to pose a threat to humans.
- Spread: Spiders can be found on almost every continent and in every environment, from deserts to tropical rainforests.
- Human benefits: Spiders play a key role in controlling insect populations, many of which are crop pests or disease vectors.
- Cultural curiosity: In many cultures, spiders have great symbolic significance. They are often associated with patience, creativity and destiny. The mythology of many cultures features the figure of a spider god or a creature with spider-like qualities.
Trivia
- Spider-balloon: Some small spiders can "fly" through the air by producing a long strand of web and letting the wind carry them into the air in a process called "ballooning." This allows them to travel long distances.
- A girl with venom: One of the world's most venomous spiders is the black widow, whose venom can be fatal to humans, although such cases are rare.
- Underwater spider: The water spider (Argyroneta aquatica) can create underwater "diving bells" with air and live underwater, hunting small fish and crustaceans.
- Nests made of leaves: Some tropical spiders make nests from leaves, gluing them together using a web.
- Largest spider: The Goliath Tarantula (Theraphosa blondi) from South America is considered the largest spider in the world in terms of body weight and leg span.
- Spiders and silk: The web of some spider species is so strong that it is being studied for use in bulletproof vests and other high-strength materials.
- Water creep: Certain species of spiders can "walk" on the surface of water thanks to surface tension, and some can even dive for food.
- Spider-chameleon: Some spiders can change their body color to adapt to their surroundings, much like a chameleon does.
- Spiders in culture: In many cultures, the spider is a symbol of creation. In African mythology, Anansi is a spider god who is a clever trickster and story-teller.
- Communications: Spiders use a variety of communication methods, including vibrations and gestures. Many species have elaborate courtship rituals in which the male must convince the female that he is a potential mate, not dinner.
