Scarus
genus of fishes
Scarus is a genus of parrotfishes. With 52 currently recognised extant species, it is by far the largest parrotfish genus. The vast majority are found at reefs in the Indo-Pacific, but a small number of species are found in the warmer parts of the eastern Pacific and the western Atlantic, with a single species, Scarus hoefleri in the eastern Atlantic.
The genus name Scarus comes from the Greek word σκάρος (skáros), which refers to parrotfishes.
Evolution
Scarus is most closely related to its sister genus Chlorurus. Most recent phylogenetic analyses find that the two genera diverged during the late Miocene (Messinian). In both genera, most of their diversification occurred some time later, within the last 3.5 million years during the Pliocene. In contrast, coral reefs in their modern form were established much earlier, during the Miocene.
Most Scarus species occur in reef habitats. Because some species such as S. zufar occur in rockier, more peripheral habitats, patterns of phylogenetic relationships have led researchers to suggest that these habitats may be the ancestral habitat type for the genus.
The public source identifies “Scarus” as genus of fishes. This brief keeps that definition visible, then builds a research path around Scarus, genus and fishes.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Scarus”, the useful work is to connect “genus of fishes” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q258514. 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
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
