Goniopora sp.*

Family Poritidae
updated Nov 2019

Where seen? This small hard coral with tiny polyps are often seen on many of of our shores, including some Northern shores. More commonly seen on our Southern shores.

Features: Colonies 10-15cm, small low dome-shaped or encrusting. The corallites are tiny (0.2cm) circular or polygonal, packed close to one another. Polyps tiny (0.5-1cm) with relatively medium length body column. Polyps can retract completely into the skeleton. Colony colours seen include pink, purple, greenish, yellow and brown.

Sometimes, tiny brown acoel flatworms are seen on the oral disk or body columns of anemone coral polyps.

May be confused with Favid corals (Family Faviidae) or Pore corals (Porites sp.), but polyp body column of these other corals are not as long as those of Goniopora corals.
