Sohal surgeonfish
species of fish
The sohal surgeonfish (Acanthurus sohal) or sohal tang, is a species of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeonfishes, unicornfishes and tangs. This fish is found in the northwestern Indian Ocean.
Taxonomy
The sohal surgeonfish was first formally described in 1775 as Chaetodon sohal by the Swedish-speaking Finnish naturalist, explorer and orientalist Peter Forsskål with its type locality given as the Red Sea. Forsskål proposed Acanthuirus as a subgenus of Chaetodon although he recognised that it was probably different from Chaetodon even at the family level. In 1856 Desmarest designated Teuthis hepatus, which had been described from a type now known to have been collected at Ambon Island in the Moluccas (other erroneous type localities were named) in 1758 by Linnaeus, as the type species of the genus. T. hepatus is a synonym of Paracanthurus hepatus and this would make Paracanthurus synonymous with Acanthurus. An alternative would be to use the name Harpurus proposed as a monospecific genus in 1788 by Johann Reinhold Forster when he described Harpurus fasciatus, a synonym of Acanthurus triostegus. It has been proposed that the International Commission on Zoological Nomenclature should be petitioned to stabilise the genera Acanthurus and Paracanthurus. In 2014 it was proposed that the type species of Acanthurus should be C. sohal, which had also been described by Forsskål in 1775 as a member of the subgenus alongside C. bifasciatus, C. nigrofuscus and C. unicornis, and had been designated as the type species by Jordan and Evermann in 1917.
Etymology
The sohal surgeonfish's specific name, sohal, is the Arabic name for this species along the Red Sea coast.
This brief starts where responsible research should: with the source description of “Sohal surgeonfish” as species of fish. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q377713. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1775, 1856, 1758 and 1788.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
