Polyphyllia


Under construction

Polyphyllia (Fungiidae)

Welcome to the Polyphyllia 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 verify what you saw underwater.  The nature of this genus is highly distinctive, which means that it is unlikely to confuse it with other members of the group.

Vital Statistics

  • 2 species
  • Coral Finder p. 25
  • COTW – Vol 2 p. 294-295

Distribution

Found in the Indo-Pacific.

ID Tips

Polyphyllia form free-living, elongate or irregular-shaped colonies.  The colonies are strongly domed in the centre, and the mouths are regularly spaced across the colony surface.  The axial furrow is generally indistinct.  Colonies may be found on reef slopes and may be locally abundant due to asexual reproduction via autotomy.

The septa and skeletal surface are hidden by short thin tentacles that are extended during the day producing a distinctive shaggy appearance.  The arrangement of septa running down the upper surface and costae running along the lower surface are characteristic of the Fungiidae.  Check out the Fungiidae training video for more information.

Similar Genera

The Coral Finder lists Polyphyllia in one key group but the thin tentacles produce a distinctive appearance, therefore there is little chance of confusion with other genera.
