Question

Which of the following does not have a poison apparatus?

Scorpion
Spider
Centipede
Crab
None of these

Answer 1

I think it is Centipede.

Answer 2

Crab does not have poison apparatus.

Explanation:

• Non-poisonous organisms do not contain poison, and only a few species of them produce toxins.
• All of the organisms listed are members of the phylum Arthropoda (jointed appendages).
• The sting of a scorpion is both painful and lethal. Their venom contains neurotoxins that affect the person's nervous system.
• Centipedes are carnivorous and poisonous; they typically attack insects and worms and rarely humans; however, when attacked, they are extremely painful and can pose a health risk.
• The spiders are almost all poisonous, with the exception of a few small ones that do not have poison; their bite is also known as the archaicism, and it causes injury.
• Crabs are a staple of many people's diets around the world; however, not all crabs are safe to consume because some may contain toxins that can be lethal but are not poisonous.
