Spider silk is five times stronger than steel by weight — making it one of the toughest biological materials known to science, and researchers have spent decades trying to synthesize it for applications from medical sutures to bulletproof vests. This quiz covers 50 questions on the 48,000+ species of spiders that share our planet.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll discover the incredible engineering of spider webs, why almost all spiders are venomous but very few are dangerous, the truth behind common spider myths, how baby spiders can fly using Earth's electric field, and why jumping spiders may be the most charismatic predators on the planet.
The Sydney funnel-web spider and the Brazilian wandering spider are generally considered the most dangerous to humans. However, antivenom exists for both, and spider bite deaths are extremely rare — far fewer than deaths from bee stings, lightning strikes, or vending machines.
No — the claim that people swallow 8 spiders per year in their sleep is completely fabricated. It originated from a 1993 magazine column that was ironically about how easily false facts spread. Spiders avoid sleeping humans due to vibrations, body heat, and breathing.
Yes — baby spiders and some adults release silk threads that catch the wind in a process called ballooning, carrying them up to 5 kilometers high and hundreds of kilometers away. Recent research suggests they can also detect and ride Earth's electric field.
