UPSC Prelims 2014 Question
Among the following organisms, which one does not belong to the class of other three? a) Crab
Answer (Detailed Solution Below)
Option 1: Crab
Detailed Solution
Explanation:
- Crabs belong to the category of crustaceans while Mite, Spider and Scorpion belong to the category of Arachnids.
- Crustaceans range in size from the Japanese spider crab, which can grow to more than four meters (13 feet), to tiny, microscopic copepods.
- All living arthropods have two key characteristics in common: hard exoskeletons and legs with joints. That last should come as no surprise. Arthropod means “jointed foot” in Greek.
Therefore, option (1) is the correct answer.
