Anacropora (Acroporidae)

Welcome to the Anacropora genus landing page. In this section, you will find general information about this genus and tips on how to identify it. If you are looking to confirm an observation made with the Coral Finder about a branching Anacropora, use the image browser below to identify a genus similar to what you saw underwater. Then choose one of the following links for further comparison with similar genera: Acropora, or Montipora.


Vital Statistics

  • 7 species
  • Coral Finder p. 1c, 3
  • COTW – Vol 1 p.168-175

Distribution

Found in Indo-Pacific.

ID Tips

Anacropora forms delicate branching thickets similar to some species of Acropora, but unlike Acropora which tends to be found in areas of good visibility, Anacropora is often confined to muddy turbid waters.

Anacropora has small radial corallites that are ‘empty’ looking, similar to Montipora and the delicate tentacles are often extended during the day.  The porous skeleton is typical of the family Acroporidae.

Similar Genera

The Coral Finder lists Anacropora in one key group with Acropora and Montipora being potential candidates for confusion.

Similar genera to branching forms of Anacropora (Coral Finder p3)

Anacropora may be confused with Acropora which forms similar branching colonies.  Anacropora however, lacks the distinctive axial corallite found on Acropora branches.

Branching forms of Montipora can be confused with Anacropora but are easily separated by the blunt branch tips and immersed corallites typical of Montipora.
