Acropora robusta

provided by wikipedia EN

Acropora robusta is a species of acroporid coral found in the Red Sea, the Gulf of Aden, the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan, the East China Sea and the oceanic west and central Pacific Ocean. It occurs in tropical shallow reefs, mainly along margins that are exposed to the action of strong waves, and can be found at depths from 1 to 8 metres (3 ft 3 in to 26 ft 3 in). It was described by Dana in 1846.

Description

It occurs in irregular colonies consisting of thick branches towards the centre, but its outer branches are thinner. Its rasp-like radial corallites can be of a variety of diameters and shapes. The species pink- or yellow-brown, cream, or bright green with branches having pinkish ends.[2]

Distribution

It is classed as a least concern species on the IUCN Red List, but it is believed that its population is decreasing, and it 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 Red Sea, the Gulf of Aden, the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan, the East China Sea and the oceanic west and central Pacific Ocean. It is found at depths between 1 and 8 metres (3 ft 3 in and 26 ft 3 in) in tropical shallow reefs mostly along margins exposed to the actions of strong waves.[1]

Taxonomy

It was described as Madrepora robusta in 1846 by Dana.[3]

Description

provided by World Register of Marine Species
Low, branching colonies, with branches sprawling in all directions, some vertically, others horizontally and then turning upwards. Branches in the centre of the colony are generally much thicker, and may simply be lumps rising from the extensive area of attachment. Branches may exceed 4 cm thick, forming some of the largest and thickest branches of the Acropora (excluding "stalks" of table Acropora). Corallites are of two main kinds: immersed or cylindrical, the latter being most common near branch tips and the former predominating on older, thicker sections. Branches have a rasp like texture. Colonies may have bases which apparently encrust the substrate for over 2 m in diameter. This species occurs in very shallow water only, where it prefers moderate rather than high exposure. It may be locally common, and completely cover areas of many square metres (Sheppard, 1998). Colonies are irregular in shape with thick conical branches at the centre and with thinner prostrate branches with upturned ends at the periphery. Radial corallites are of mixed size and shapes but are generally rasp-like. Colour: bright green with deep-pink branch tips or pinky-brown, yellow -brown or cream. Abundance: Restricted to shallow reef environments, common on reef margins exposed to strong wave action (Veron, 1986).
