context_page_description: Goniopora columna is a species of colonial stony coral in the family Poritidae.
context_section_description: This species develops hemispherical or irregular columnar  mound shaped colonies  with a neat appearance and dead basal parts. The color of the polips may be yellow, brown or green, usually with different color in the oral discs. 
  The diameter of the small and rounded calices ranges from about 3–5 mm (0.12–0.20 in), with a uniform bundle of tentacles. The columellae are rather large and long. The living polyps can reach a length up to 10 cm (3.9 in). 
  This species is quite similar to Goniopora stokesi and Goniopora lobata. It differs from the other two especially for the columnar shape of the colonies and for the large light-colored oral disc.
