The sand wrasse, Ammolabrus dicrus, is a species of wrasse endemic to Oahu, Hawaii. They prefer open, sandy substrates, where they hunt for zooplankton near the ocean floor. They can be found at depths of 7 to 18 m (20 to 60 ft) in small schools. This species grows to a length of 9.4 cm (3.7 in). This species is the only known member of its genus.

Editorial summary

The public source identifies “Sand wrasse” as species of fish. This brief keeps that definition visible, then builds a research path around Sand, wrasse and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 67-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Sand, wrasse and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Sand wrasse”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.

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 Jul 29, 2026. The linked authority identifier is Q1758448. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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
