Which eight-legged animal is poisonous and feared by many?

• A. Scorpion
• B. Spider
• C. Centipede
• D. Tick

Answer: (B)

Eight-legged arachnids that deliver venom through fangs are spiders. This combination—having eight legs and using venom to subdue prey—makes spiders the creature most commonly described as both venomous and feared. Many people know spiders primarily for their appearance and the potential bite, even though most species aren’t dangerous to humans. The other possibilities don’t fit as well: scorpions also have eight legs and can sting with venom, but they’re not the standard image people think of when they say someone fears an eight-legged creature; centipedes have many more than eight legs; ticks have eight legs as adults but aren’t venomous and harm mainly through bloodsucking and disease transmission. So the spider is the best match.
