Goniastrea


Under construction

Goniastrea (Faviidae)

Welcome to the Goniastrea 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, use the image browser below to identify a growth form or corallite structure similar to what you saw underwater. Then choose one of the following links for further comparison with similar genera: meandering, or cerioid corallites.

Like other members of the Faviidae family Goniastrea is widespread in the Indo-Pacific, exploiting a large range of environmental conditions.  Goniastrea however, has taken this one step further by dominating intertidal areas, where resistance to aerial exposure is vital.  Exposure is associated with an interesting array of skeletal modifications!

Vital Statistics

  • 13 species
  • Coral Finder p. 4c, 8, 8c, 13, 14
  • COTW – Vol 3 p.156-175

Distribution

Widespread in the Indo-Pacific.

ID Tips

Goniastrea forms massive mounds, thick encrusting colonies or may tend towards columns.  Colonies are common in sub-tidal and some inter-tidal areas.

The corallites of Goniastrea vary along a spectrum from single-mouth, rounded with shared walls through to multiple-mouth, weakly meandering with thin shared walls.  A key feature of Goniastrea is the paliform crown; a ring of skeletal teeth surrounding the columella.  Corallites are neat with fine, uniform septa.

Similar Genera

The Coral Finder lists Goniastrea with Favites, and Platygyra being potential sources of confusion.

Similar genera to meandering Goniastrea (Coral Finder p8)

Meandering forms of Goniastrea can be confused with Platygyra but are easily separated by the paliform crown typical of Goniastrea. Platygyra does not possess paliform lobes and the corallites are less regular and neat.

Meandering Goniastrea

Similar genus: Platygyra

Similar genera to cerioid Goniastrea (Coral Finder p13-14)

Identification issues may arise between Favites and Goniastrea where corallites are cerioid or sub-meandroid.  The Cerioid/Plocoid Learning Groups and Asexual Reproduction pages provide detailed descriptions and clear photos to assist in untangling any initial difficulties in identifying these genera.  Links for the Learning Groups  and Asexual Reproduction articles are provided in the Learning Resources section below.

Cerioid Goniastrea

Similar genus: Favites

Ecology

The environmental tolerance of Goniastrea ensures that this genus dominates in intertidal reefal areas where many other corals cannot survive the stress of the cyclical aerial exposure of the tides.  Colonies may form ‘micro-atolls’ where the living band of tissue is limited to the flanks of the colony.
