Target class: reef-building organism
Context triple: [Archaeocyatha, instanceOf, reef-building organism]

• A. marine reef formation
  Marine reef formation is the long-term process by which corals and other calcifying organisms build and accumulate calcium carbonate structures that create complex, biodiverse underwater habitats.
• B. coral reef system
  A coral reef system is a complex, living marine ecosystem composed of coral organisms and their associated species, interacting with physical and chemical ocean conditions to form a highly biodiverse and productive habitat.
• C. rugose coral chosen
  A rugose coral is an extinct order of solitary or colonial Paleozoic corals characterized by horn-shaped or wrinkled calcareous skeletons with well-defined internal septa.
• D. freshwater polyp
  A freshwater polyp is a small, simple aquatic invertebrate (such as a hydra) that lives in non-saline water and typically has a tubular body with tentacles used for feeding.
• E. coral reef wall
  A coral reef wall is a steep, often vertical underwater slope densely covered with diverse coral formations and marine life, forming a dramatic boundary between shallow reef tops and deeper ocean waters.
• F. None of above.
