Source-derived summary

Genicanthus watanabei, the blackedged angelfish or Watanabe's angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the Pacific Ocean.

Description

Genicanthus watanabei, like the other angelfishes in the genus Genicanthus, shows sexual dichromatism, the males and females show differences in colour and pattern. The males are pale blue to bluish-grey on the upper third of their bodies with the lower two thirds having 8 horizontal, thin black stripes, the highest of these end in a patch of yellow colour. The females are overall light blue colour with wide black bars across their head and a black spot on the snout. In both males and females there is a wide submarginal band on the dorsal and anal fins, and on the lobes of the caudal fin. Juveniles somewhat resemble females in colour. In both sexes the forked tail narrows at its base to create a "swallow tail". The dorsal fin contains 15-16 spines and 15-16 soft rays while the anal fin has 3 spines and 14-17 soft rays. This species attains a maximum total length of 15 centimetres (5.9 in).

Editorial summary

This brief starts where responsible research should: with the source description of “Genicanthus watanabei” as species of marine angelfish. 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 190-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 Genicanthus, watanabei and species 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 marine angelfish. 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 21, 2026. The linked authority identifier is Q4543204. 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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
