Platygyra daedalea
species of cnidarian
Platygyra daedalea, sometimes known as the lesser valley coral, is a colonial species of stony coral in the family Merulinidae. It occurs on reefs in shallow water in the Indo-Pacific region. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Description
Platygyra daedalea usually forms massive dome or boulder-shaped colonies which may be a metre (yard) or more in diameter; however, sometimes it forms flattened plates or it may be encrusting. The polyps are situated in meandering valleys with low walls between them which are often perforated. The septa are toothed and protuberant, usually with uneven or pointed tips. There is an obvious ridge, the columella, in the centre of the valley. The colour varies and there may be contrasting valleys and ridges. This coral can be distinguished from the similar but less common Platygyra lamellina by the fact that the valleys are wider and the walls between them have more vertical sides and have flatter tops.
Distribution and habitat
Platygyra daedalea is a common species with a widespread distribution in the Indo-Pacific region.
The public source identifies “Platygyra daedalea” as species of cnidarian. This brief keeps that definition visible, then builds a research path around Platygyra, daedalea and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Platygyra daedalea”, the useful work is to connect “species of cnidarian” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q3943742. 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 source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
