thân giáp

Definition
  1. Noun:
    • Crustacean: A member of a large class (Crustacea) of arthropod animals, typically having a hard shell (exoskeleton), two pairs of antennae, and living in aquatic environments. Examples include crabs, lobsters, shrimp, and crayfish.
Usage Examples
  • Noun:
    • Tôm và cua là những loài thân giáp phổ biến. (Shrimp and crabs are common crustaceans.)
    • Nhiều loài thân giáp sống ở biển. (Many crustaceans live in the sea.)
    • Lớp vỏ cứng bảo vệ cơ thể của thân giáp. (The hard shell protects the crustacean's body.)
Advanced Usage
  • The term "thân giáp" is a scientific and formal term. In everyday conversation, people usually refer to specific animals like (shrimp), (crab), or (lobster) rather than using the general class name.
Variants and Related Words
  • Giáp xác: This is the more common and modern Vietnamese term for "crustacean." It is synonymous with "thân giáp".
    • Ngành giáp xác có rất nhiều loài. (The crustacean group has many species.)
Synonyms
  • Crustacean: The direct English equivalent.
  • Shellfish (note): This common English term is broader and can include some mollusks (like mussels, oysters) that are not crustaceans. It is a culinary and general term, not a precise scientific synonym.
Notes on Usage
  • "Thân giáp" is a classical compound word: (body) + (armor), literally meaning "armored body," which accurately describes the animal's hard exoskeleton.
  • While "thân giáp" is correct and understood, the term "giáp xác" is more frequently used in contemporary Vietnamese, especially in scientific and educational contexts.
