Source-derived summary

The spot-tail shark, or sorrah shark (Carcharhinus sorrah), is a species of requiem shark, in the family Carcharhinidae, found in the tropical Indo-West Pacific Ocean between latitudes 31°N and 31°S from the surface to a depth around 72 m (236 ft). This shark grows to about 1.6 m (5 ft 3 in). It is fished commercially over much of its range and the IUCN considers it to be near threatened.

Etymology

The species name sorrah originates from சுறா ("sura"), the Tamil word for "shark".

Description

The spot-tail shark is a spindle-shaped fish growing to about 1.6 m (5 ft 3 in). It has a fairly long, pointed snout and moderately large eyes. The first dorsal fin is large and curved, while the second dorsal fin is small and low. The back and sides are grey and the belly white, and a long white streak is on the flank. This species can be distinguished from other requiem sharks found in tropical waters by the distinctive black tips to the second dorsal fin, the pectoral fins, and the lower lobe of the caudal fin. A ridge over the spine extends from the first to the second dorsal fin and a pit just in front of the upper lobe of the caudal fin.

Editorial summary

The public source identifies “Spot-tail shark” as species of shark. This brief keeps that definition visible, then builds a research path around Spot-tail, shark and species.

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 210-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 Spot-tail, shark 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 “Spot-tail shark”, the useful work is to connect “species of shark” to the records capable of establishing context and consequence.

Evidence profile

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 12, 2026. The linked authority identifier is Q210052. 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.
