"S. arabica" is similar in morphology to other sillaginids, although has a distinctive shortened snout which gives the species its common name. This species is of no current interest to local fisheries, although beach seines may take minor amounts of this species.Taxonomy and naming
The shortnose whiting belongs to the
genus "Sillago ", a subdivision of the smelt whiting familySillaginidae . The Sillaginidae are in thesuborder Percoidei , [ITIS | ID = 646037 | taxon = Sillago arabica | year = 2008 | date = 05 May] a division of thePerciformes .FishBase species | genus = Sillago | species = arabica | year = 2008 | month = Jul ]The
species was identified and named "Sillago arabica" by Roland McKay and L.J. McCarthy in 1989, after examining theholotype which was initially collected inTanajib Bay in thePersian Gulf during 1982.cite journal | last = McKay | first = Roland J. | coauthors = McCarthy, L.J. | title = A revision of the sillaginid fish of the Arabian Gulf with a description of "Sillago arabica" new species | journal = Memoirs of the Queensland Museum | volume = 27 | issue = 2 | pages = 551-554 | date = 1989 | url = | doi = | id = | accessdate = 2008-05-12 ] The authors also termed thecommon name 'shortnose whiting' for the species, as its uniquely shortsnout is a key identifying feature in the field. cite book | last = McKay | first = R.J. | coauthors = | title = FAO Species Catalogue: Vol. 14.

The shortnose whiting shares the same basic profile as most of the "
Sillago " genus, possessing an elongate, slightly compressed body tapering toward the terminal mouth. The profile of the species is slightly leaner than most of its close relatives, which may be one initial key to field identification. More definitivediagnostic features include thespine and ray count of the dorsal andanal fin s as well as the morphology of theswim bladder . The first dorsal fin consists of 12 or 13 spines, while the second dorsal fin has one spine and 22 to 24 soft rays posterior to the spine. The anal fin is similar to the second dorsal fin with 2 spines followed by 22 to 24 soft rays. The species has 75 to 80lateral line scales and a total of 38 to 40vertebrae , also diagnostic features. ] . The species is one of the smaller whitings, growing only to a maximum length of 15cm overall. ] The swim bladder of "S. arabica" has no anterior extensions and a single posterior extension. The anterior margin of the organ is slightly rounded, while aduct like tubular process extends from the ventral surface to theurogenital opening.The species has pale sandy brown colour overall, with a slightly paler
belly and slightly darker upper operculum. There are no dark blotches present on the side of the fish, while the first and second dorsal fins and caudal fin are dusted with black. ]Distribution and habitat
The shortnose whiting is entirely restricted to the
Persian Gulf , where it inhabits the shallowcoastal waters out to a depth of 5m. The species is often caught inseine net s alongbeach es in the Gulf, although nofishery exists for the species. As mentioned previously, the species has had very little data collected on it, with the initial description by McKay and McCarthy in 1989 the only major study on the species. ]References
