Acropora tenuis
species of cnidarian
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.
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. 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.
Biology
Acropora tenuis is a simultaneous hermaphrodite. Spawning takes place once a year and is synchronised among the colonies in any one locality.
This brief starts where responsible research should: with the source description of “Acropora tenuis” as species of cnidarian. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of cnidarian. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q3946173. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
