Source-derived summary

The Gulf torpedo (Torpedo sinuspersici) or variable electric ray, is a species of electric ray in the family Torpedinidae. It is found in the Indian Ocean, but may represent a species flock of several local endemic species. It is distinguishable from other Torpedo species in its range by its ornate dorsal coloration. Another common name, marbled electric ray, is not to be confused with Torpedo marmorata.

Distribution and habitat

The Gulf torpedo is the most widespread of the electric rays in the western Indian Ocean, with a patchy range extending to South Africa, Somalia, the Red Sea, the Arabian Sea, the Persian Gulf, Sri Lanka, and the Andaman Sea. There are also less reliable reports of it occurring elsewhere, including Madagascar, the Seychelles, and the Laccadive Islands. Recorded for the first time in 2002 in Mediterranean Sea, its presence needs to be clarified due to its strong resemblance with Torpedo marmorata, a species well established there. It is found in shallow waters in sandy areas, on and near coral reefs, and offshore to a depth of 150 meters. It often buries itself in the sandy bottom of gullies and estuaries. The Gulf torpedo occurs in water temperatures of 20–29 °C (68–84 °F).

Editorial summary

The public source identifies “Gulf torpedo” as species of fish. This brief keeps that definition visible, then builds a research path around Gulf, torpedo 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 lead gives the account dated anchors—2002—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Gulf, torpedo 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 “Gulf torpedo”, the useful work is to connect “species of fish” 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 May 19, 2026. The linked authority identifier is Q149333. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2002.

Critical limits

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.
