Which term specifically refers to reef-building corals?

• A. Ahermatypic
• B. Medusa
• C. Lateral-Line System
• D. Hermatypic

Answer: (D)

Reef-building corals are hermatypic. These corals host photosynthetic algae called zooxanthellae within their tissues, which provide energy through photosynthesis and enable rapid calcium carbonate deposition to form and grow reef structures. In contrast, ahermatypic corals do not build reefs, often lacking or having limited zooxanthellae and growing much more slowly. Medusa is a separate life stage in cnidarians and not related to reef construction, and the lateral-line system is a sensory organ in fish. So the term specifically referring to reef-building corals is hermatypic.
