Acropora tenuis is a species of acroporid coral found in the Red Sea, the Gulf of Aden, the southwest, northwest and northern Indian Ocean, the Persian Gulf, 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 on upper slopes and in subtidal habitats, at depths of 8 to 20 metres (26 to 66 ft).

Description

It occurs in corymbose colonies containing orderly-spaced branchlets. It has tube-shaped axial corallites and radial corallites have flaring lips. It is blue, cream, yellow or green in colour, and is similar to Acropora vermiculata . [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 Red Sea, the Gulf of Aden, the southwest, northwest and northern Indian Ocean, the Persian Gulf, the central Indo-Pacific, Australia, Southeast Asia, Japan, the East China Sea, and the oceanic western and central Pacific Ocean. It is found at depths of between 8 and 20 metres (26 and 66 ft) in tropical shallow reefs on upper slopes and in subtidal areas. [1]

Biology

Acropora tenuis is a simultaneous hermaphrodite. Spawning takes place once a year and is synchronised among the colonies in any one locality. Packets of eggs and sperm are released into the water column and, being buoyant, rise to the surface. Here the packets break up and cross-fertilisation takes place with gametes from different colonies intermixing. [3]

<i>Acropora abrotanoides</i> Species of coral

Acropora abrotanoides is a species of acroporid coral found in Indo-Pacific waters from the Red Sea and the Gulf of Aden east to the East China Sea, Japan, the central Pacific Ocean and Australia. It is found in shallow coral reefs that are exposed to the action of strong waves, at depths up to 15 m. It is vulnerable to coral bleaching, disease and crown-of-thorns starfish. It is resistant to predation as it has well-developed radial corallite lips.
