Datnioides polota
species of fish
Datnioides polota, the silver tigerfish, silver tiger perch, barred tigerfish, four-banded tripletail, four-banded tigerfish or four-barred tigerfish, is a species of ray-finned fish belonging to the family Lobotidae, the tripletails and tiger perches. This fish is found in southern Asia and New Guinea.
Taxonomy
Datnioides polota was first formally described as Coius polota by the Scottish geographer and naturalist Francis Buchanan-Hamilton with its type locality given as the estuaries of the River Ganges in India. In 1853 Pieter Bleeker proposed the genus Datnioides and in 1876 he designated D. polota as its type species. In 2000 Maurice Kottelat determined that the type species of the genus Coius, Coius cobojius, was a junior synonym of Anabas testudineus so Coius is a junior synonym of Anabas, with Datnioides being the correct name for the tiger perch genus. The 5th edition of the Fishes of the World classifies this genus as one of two genera in the family Lobotidae, alongside the tripletails in the genus Lobotes, which it places in the order Spariformes.
Etymology
Datnioides polota has a specific name, polota, which Hamilton did not explain. It is thought to be a local name for this fish in the Ganges of India.
Description
Datnioides polota has its dorsal fin supported by 12 spines and 13 or 14 soft rays while the anal fin contains 3 spones and 8 or 9 soft rays. The maximum published standard length of this species is 30 cm (12 in), although 18 cm (7.1 in) is more typical.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Datnioides polota”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
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 17, 2026. The linked authority identifier is Q2910272. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1853, 1876 and 2000.
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
