Sillago maculata, commonly known as the Trumpeter Whiting, is a species of inshore marine fish belonging to the family Sillaginidae. It is characterized by its elongated body, distinctive spotted coloration, and a relatively small mouth. This species is a popular target for recreational and commercial fisheries throughout its range due to its palatable flesh.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Dorsal surface is typically pale brown to yellowish-brown, fading to white or silvery on the ventral side. The most distinctive feature is a series of irregular, dark brown to black blotches or spots along the lateral line and upper flanks, often forming indistinct bars. Fins are generally translucent to yellowish, with the caudal fin sometimes having a dusky margin.
- Scale type
- ctenoid
- Mouth position
- subterminal
- Distinctive features
- Elongated, slightly compressed body, Distinctive dark blotches/spots along the lateral line and upper flanks, Two dorsal fins, the first with strong spines, Small, slightly inferior mouth
- Dorsal fin
- Two dorsal fins; the first with 10-11 strong spines, the second with 1 spine and 17-19 soft rays. The first dorsal fin is typically higher than the second.
- Tail fin
- Caudal fin is slightly forked or truncate.
- Pectoral fin
- Pectoral fins are moderately long, reaching to or slightly beyond the origin of the second dorsal fin.
- Distinctive fins
- Pelvic fins are thoracic, with 1 spine and 5 soft rays. Anal fin has 2 spines and 17-19 soft rays, similar in length to the second dorsal fin.
Identification Tips
Body Shape and Coloration
Look for the elongated, slender body with a pale brown to yellowish-brown back and silvery-white belly. The most reliable identifier is the presence of distinct, irregular dark blotches or spots along the sides, particularly above the lateral line.
Dorsal Fins
Note the two dorsal fins. The first dorsal fin is spiny and noticeably taller than the second, soft-rayed dorsal fin.
Mouth Position
The mouth is relatively small and slightly inferior (subterminal), indicating its bottom-feeding habits.
Lateral Line
The lateral line is complete and runs along the mid-flank, often with the characteristic dark spots concentrated along or just above it.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters, from the surf zone to depths of about 60 meters (200 feet).
- Environment
- Inhabits sandy and muddy substrates in estuaries, bays, coastal lagoons, and open coastal areas. Often found near seagrass beds and mangroves, especially juveniles.
- Geographic range
- Indo-West Pacific region, including the coasts of Australia (primarily Queensland and New South Wales), Papua New Guinea, Indonesia, Philippines, and extending north to Japan and west to India.

Key Facts
Bottom Feederbehavior
Trumpeter Whiting primarily feed on benthic invertebrates, using their small, subterminal mouths to sift through sand and mud for prey.
Nocturnal Foragerbehavior
While often caught during the day, Trumpeter Whiting are known to be more active foragers during twilight and nocturnal hours.
Schooling Behaviorbehavior
Juvenile and adult Trumpeter Whiting often form schools, particularly in estuarine and shallow coastal areas, which aids in foraging and protection from predators.
Rapid Growthinteresting
This species exhibits relatively rapid growth, reaching marketable size within a year or two, contributing to its importance in fisheries.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: Trumpeter Whiting are generally safe to handle. Care should be taken with the spines of the first dorsal fin, as they can cause minor punctures if not handled carefully. No venom is associated with these spines.
Similar Species
Eastern School Whiting
Sillago flindersi
Sillago flindersi generally lacks the prominent dark blotches of S. maculata, having a more uniform silvery coloration or faint dusky markings. Its body is typically more slender, and it often inhabits deeper waters.
Sand Whiting
Sillago ciliata
Sillago ciliata usually has a more uniform silvery-white body without distinct dark blotches, though it may have faint dusky bars. Its pectoral fins are often yellowish, and it typically has a more prominent dark spot at the base of the pectoral fin, which is usually absent or very faint in S. maculata.
Golden-lined Whiting
Sillago analis
Sillago analis is distinguished by a prominent golden or yellowish stripe running along its lateral line, which is absent in S. maculata. It also lacks the distinct dark blotches.
