Acropora granulosa

provided by wikipedia EN

Acropora granulosa is a species of acroporid coral found in the northern and southwest Indian Ocean, the Red Sea, Australia, the East China Sea, Japan, the oceanic central and western Pacific Ocean, and the central Indo-Pacific. It occurs in tropical shallow reefs, from depths of between 8 and 40 metres (26 and 131 ft). It was described by Milne Edwards in 1860 and is classified as near threatened by the IUCN.

Description

It is found in colonies composed of a single horizontal plate of branches with a diameter below 1 metre (39 in). Branches are evenly spaced and branchlets are short and inclined. Each branchlet has at least one incipient axial and axial corallite, and its small radial corallites are pocket-shaped. There are no known similar-looking species, and it is mostly pale blue, cream or grey in colour.[2]

Distribution

It is classed as a near threatened species on the IUCN Red List and it is believed that its population is decreasing; the species is listed under Appendix II of CITES. Figures of its population are unknown, but is likely to be threatened by the global reduction of coral reefs, the increase of temperature causing coral bleaching, climate change, human activity, the crown-of-thorns starfish (Acanthaster planci) and disease.[1] It occurs in the northern and southwest Indian Ocean, the Red Sea, Australia, the East China Sea, Japan, the oceanic central and western Pacific Ocean, and the central Indo-Pacific. It is found at depths of between 8 and 40 metres (26 and 131 ft) in tropical shallow reefs.[1]

Taxonomy

It was described as Madrepora granulosa by Milne Edwards in 1860.[3]

Description

provided by World Register of Marine Species
Colonies are usually less than 30 cm across and high, with bushy form, and only a limited tendency towards developing into plates. Where they do form plates, the branches are often flattened: there is a flat, granular underside with no branches arising from the surface, and a rounded upper side which supports the branchlets. Branchlets are very distinctive, due to their very large and smoothly rounded, often bulbous, axial corallites. Each axial corallite can exceed 1.5 cm long and 6 mm wide, and may comprise over half of its entire branchlet. Generally, radial corallites do not appear until well down the branchlets, though on the more bulbous axials, several completely immersed radials develop. This species is seldom seen in shallow water but prefers depths of 15 to 40 m deep in clear water. Although it is widespread its fairly small colonies are well dispersed, and it does not form dense aggregations. The large axial corallites are cream coloured, with the rest of the colony being pale or mid brown (Sheppard, 1998). Colonies are semicircular horizontal plates less than 1 m across, composed of regularly spaced horizontal branches with short upright branchlets with tapering tubular corallites. Colour: usually uniform cream, grey or pale blue, but may be other colours. Abundance: Seldom found in shallow water but common on lower reef slopes (Veron, 1986).
