9 Fun Facts about Spiders


Spiders are air-breathing arthropods with 8 legs, chelicerae with fangs usually able to introduce venom, and spinnerets that extrude silk. They are the most significant order of arachnids and rank 7th in total species diversity amongst all orders of organisms.

People are mostly scared of spiders because some of them are poisonous. Other people freeze at the thought of being snapped. Let’s explore spiders with nine fun facts.

  1. Though spiders have large eyes, they usually are not well refined. Instead, spiders utilize vibrations, which they can sense on the outside of their web. The tiny fibers distributed all over a spider’s body surface, are sensitive tactile receptors. These bristles are susceptible to a variety of stimuli, including vibration, airflow, and touch.
  2. Spiders are arthropods, so the skeletal arrangement of their body is the surface layer. The durable exoskeleton helps the spider manage moisture and not dry out. The bristles are not hair, but piece of their exoskeleton.
  3. The word spider is from an Early English word spinnan, meaning “to spin.” Web weavers use the little claws at the base of each leg and their rough hairs, to walk on their webs without clinging to them.
  4. Spiders ingest their food outside their body. After the prey is caught, spiders issue digestive enzymes from their internal tract and cover the insect. These ferments break down the body, which enables the spider to suck up the thawed prey.
  5. The dreaded tarantula isn’t fatal. A tarantula’s bite can be unpleasant, but it isn’t any more hazardous than a bee sting.
  6. A Daddy-long-legs isn’t a spider, though it resembles one. It doesn’t have a diaphragm between its front body part and its belly. Its legs are longer and lighter than a spider’s, and it moves its body hung low.
  7. Under a spider’s belly, near the back, are small stubs called spinnerets. The spider uses its limbs to pull liquid silk made in its stomach from the spinnerets. The silk contracts as it stretches. Since silk is made out of protein, a spider consumes the used silk of an old web before producing a new one.
  8. Not all spiders spin webs, but many use silk in other ways. Some spiders are known to defend their eggs in silken egg sacs. The Wolf Spider carries her egg sac connected to her spinnerets. Many tarantulas line their dens with silk. Some trap-door spiders make soft lids for their burrows.
  9. If you stare at your dollar bills carefully, you will find what seems to be a tiny spider right near the large “1” at the top right of the dollar bill. You will see this in the upper-left area of the guard that encompasses the “1.”
