Goniopora columna

provided by wikipedia EN

Goniopora columna is a species of colonial stony coral in the family Poritidae.[2]

Distribution

This species is native to the western and eastern Indian Ocean and the western Pacific Ocean, including the Red Sea, the Gulf of Aden, the Persian Gulf, Australia, South-east Asia, Japan and East China Sea.

It can be found in Australia, Bahrain, Cambodia, China, Comoros, Djibouti, Egypt, Eritrea, Fiji, Guam, India, Indonesia, Iran, Iraq, Israel, Japan, Jordan, Kuwait, Madagascar, Malaysia, Maldives, Marshall Islands, Mauritius, Micronesia, Mozambique. Myanmar, New Caledonia, Mariana Islands, Oman, Pakistan, Palau, Papua New Guinea, Philippines, Qatar, Réunion, Saudi Arabia, Seychelles, Singapore, Solomon Islands, Somalia, Sri Lanka, Sudan, Taiwan, Thailand, United Arab Emirates, Viet Nam and Yemen.[1]

Habitat

This reef-associated species occurs in tropical shallow waters and in sheltered, sandy or lagoon environments, at depths of 2 to 15 m. It may also occur in turbid waters. The International Union for Conservation of Nature has assessed its conservation status as being "Near Threatened". These corals appear moderately susceptible to bleaching, especially in turbid waters, which can help to protect them.[1]

Description

Colonies of Goniopora columna in Thailandia

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).[3][4][5]

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.

Biology

Like most corals, Goniopora columna reproduce asexually. They usually feed on plankton. Mature gametes are spawned through the mouth. The zygote develops into a planktonic planula larva.[6][7]

Description

provided by World Register of Marine Species
Colonies develop columns with dead basal parts. Calice diameters are variable and range from about 3 to 5 mm diameter, with most being no larger than about 3.5 mm. Columellae are large. The coral has a much neater appearance than the "ragged" structure of G. stokesi calices. Living polyps are up to 10 cm long. This is probably the commonest Goniopora in the Arabian region and Indian Ocean generally. It is common in sheltered, sandy or lagoonal areas where it develops columnar colonies in the manner of G. stokesi, though usually not so large. It is common at all depths between 2 and 15 m deep in such habitats. (Sheppard, 1998 <308>) Colonies are short columns, oval in transverse section. Calices are 3.5-4.5 mm in diameter. Those near the tops of columns have fine irregular septa and diffuse columellae. Those on the sides of columns have broad compact columellae and short septa. Living colonies have large polyps. Colour: brown, green or yellow. Contracted polyps usually have distinctly different colours. Abundance: Common, forms large monospecific stands especially in turbid water. (Veron, 1986 <57>)
