Sillago vittata, commonly known as the Western School Whiting, is a species of marine ray-finned fish belonging to the family Sillaginidae, the smelt-whitings. It is a small, slender fish characterized by its silvery body and distinctive dark blotches or bands along its flanks. This species is an important component of coastal ecosystems in Western Australia and is targeted by both commercial and recreational fisheries.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Silvery-white to pale brown dorsally, fading to white ventrally. Distinctive series of 7-10 dark, oblique blotches or bands along the lateral line, often more prominent in juveniles and freshly caught specimens. Fins are generally hyaline (clear) to slightly dusky.
- Scale type
- ctenoid
- Mouth position
- terminal
- Distinctive features
- Elongated, slender body, Small, pointed head, Two dorsal fins, the first spiny and the second soft-rayed, Distinctive dark blotches/bands along the lateral line, Small, terminal mouth
- Dorsal fin
- First dorsal fin with 10-11 spines; second dorsal fin with 1 spine and 16-18 soft rays. The two dorsal fins are distinctly separated.
- Tail fin
- Caudal fin emarginate (slightly forked) to truncate.
- Pectoral fin
- Pectoral fins are relatively long, reaching to or beyond the origin of the second dorsal fin.
- Distinctive fins
- Anal fin with 2 spines and 16-18 soft rays. Pelvic fins thoracic.
Identification Tips
Body Shape
Look for a slender, elongated body typical of whiting species.
Coloration and Markings
The most distinguishing feature is the series of 7-10 dark, oblique blotches or bands along the lateral line. These can fade quickly after capture.
Dorsal Fins
Note the two distinct dorsal fins, with the first being spiny and the second soft-rayed.
Pectoral Fin Length
The pectoral fins are relatively long, often reaching past the origin of the second dorsal fin.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters, from the surf zone to depths of about 50 meters.
- Environment
- Inhabits sandy and silty substrates in bays, estuaries, coastal beaches, and offshore reefs. Often found in seagrass beds and near rocky outcrops.
- Geographic range
- Endemic to Western Australia, ranging from the North West Shelf southwards to the Great Australian Bight, including Shark Bay and the Perth metropolitan area.

Key Facts
Endemic to Western Australiainteresting
Sillago vittata is found exclusively in the coastal waters of Western Australia, making it a unique regional species.
Dietary Habitsbehavior
This species is a benthic feeder, primarily consuming small crustaceans (like prawns and amphipods), polychaete worms, and other small invertebrates found in sandy and silty substrates.
Schooling Behaviorbehavior
As its common name 'School Whiting' suggests, this species often forms schools, particularly when foraging or during spawning aggregations.
Ecological Roleinteresting
Western School Whiting plays an important role in its ecosystem as a predator of small invertebrates and a prey item for larger fish and seabirds.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions are required beyond standard fish handling practices to avoid fin pricks. The spines are not venomous.
Similar Species
Western Sand Whiting
Sillago schomburgkii
S. schomburgkii generally lacks the distinct dark blotches/bands along the lateral line that are characteristic of S. vittata. S. schomburgkii often has a more uniform silvery coloration or faint, irregular blotches, and its pectoral fins are typically shorter, not reaching the second dorsal fin origin.
Yellowfin Whiting
Sillago analis
S. analis is distinguished by its prominent yellow pectoral and caudal fins, which are not present in S. vittata. S. analis also lacks the distinct dark body blotches of S. vittata.
Trumpeter Whiting
Sillago maculata
While 'Trumpeter Whiting' is an alternative name for S. vittata, the true S. maculata (Spotted Whiting) is found in eastern Australia and has more numerous, smaller, and often more circular dark spots or blotches scattered over its body, rather than the distinct oblique bands of S. vittata.
