NMITA: Neogene Marine Biota of Tropical America

Tool for identifying zooxanthellate coral genera

Check one state for each of the seven characters; missing values are not allowed.
Click on character state name for illustrations and definition of that state.
Use character states marked with * for demonstration purposes

  2. Plocoid
    Meandroid *
  3. Colony Shape: The overall shape of a colony.

  4. Mostly massive or encrusting
    Mostly branching
    Mostly platy (one-side) *
  5. Budding: The position of newly budded corallites relative to the corallite wall.

  6. Mostly intramural *
    Mostly extramural
  7. Columella: The central axial structure within a corallite.
