Source-derived summary

Eusmilia is a genus of stony coral in the family Meandrinidae. It is a monotypic genus represented by the species Eusmilia fastigiata, commonly known as the smooth flower coral. It is found on reefs in the Caribbean Sea.

Description

Smooth flower coral is a colonial species that grows to about 50 centimetres (20 in) across. It forms a low mound of stony calcium carbonate, the surface of which is covered with tubular projections, the corallites, in groups of one to three. The polyps protrude from these and are either round or oval, with the oval form being more common at moderate depths. They are large and widely spaced and are connected by a layer of translucent, jelly-like mesoglea tissue called coenosarc which covers the surface of the carbonate skeleton. During the day they are retracted back into the cup-shaped corallites. These have large smooth-edged ridges called septa, and the polyps have corresponding grooves at their base. At night, the polyps stretch out their translucent white tentacles to feed and the coral "flowers".

Editorial summary

This brief starts where responsible research should: with the source description of “Eusmilia” as species of cnidarian. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 172-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Eusmilia, species and cnidarian can be independently traced.
Editorial analysis

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.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q2785489. None of the 0 selected statements returned an explicit reference.

Critical limits

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.

Three-step research path

  1. Establish the record: confirm the title “Eusmilia”, its source revision and the description used here.
  2. Expand the search: follow Eusmilia primary sources, Eusmilia archive and Eusmilia research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.

Questions for further research

  1. Which source most directly establishes the central claim about “Eusmilia”?
  2. Is the terminology current, historical or disputed?
  3. Which observation, specimen, dataset or publication supports the account?
