Scomberomorus guttatus, commonly known as the Indo-Pacific King Mackerel or Spotted Spanish Mackerel, is a pelagic, predatory fish belonging to the family Scombridae. It is highly valued as a food fish and is a popular target for both commercial and recreational fisheries throughout its range. This species is characterized by its streamlined body, sharp teeth, and distinctive spotted coloration, which aids in camouflage in its open water habitat.
Caratteristiche fisiche
- Forma del corpo
- torpedo
- Colorazione
- Dorsal surface iridescent blue-green, fading to silvery on the flanks and belly. Distinctive feature is the presence of several irregular rows of dark, round to oval spots on the sides, which become more prominent with age. The first dorsal fin is dark.
- Tipo di squame
- none
- Posizione della bocca
- terminal
- Caratteristiche distintive
- Streamlined, fusiform body adapted for fast swimming., Laterally compressed., Large, conical mouth with a single row of strong, triangular, compressed teeth in each jaw., Absence of scales on the corselet (a patch of larger, thicker scales behind the head and around the pectoral fin base) and body, except for the lateral line., Presence of 8-10 dorsal and 7-10 anal finlets behind the second dorsal and anal fins, respectively., Caudal peduncle with a prominent median keel and two smaller keels on either side.
- Pinna dorsale
- Two dorsal fins; the first is long with 15-18 spines, originating above the pectoral fin base. The second dorsal fin is much shorter with 15-19 soft rays, followed by 8-10 finlets.
- Pinna caudale
- Deeply forked caudal fin, characteristic of fast-swimming pelagic fish.
- Pinna pettorale
- Short, pointed pectoral fins with 21-24 rays, located high on the body.
- Pinne distintive
- Pelvic fins are small and located below the pectoral fins. Anal fin is similar in shape and size to the second dorsal fin, with 16-20 soft rays, followed by 7-10 finlets.
Consigli per l'identificazione
Body Shape and Coloration
Look for the torpedo-shaped body, iridescent blue-green back, silvery sides, and distinct irregular rows of dark, round to oval spots on the flanks. The first dorsal fin is dark.
Finlets
Count the finlets behind the second dorsal and anal fins (8-10 dorsal, 7-10 anal). This is a key characteristic of Scombridae.
Lateral Line
Observe the lateral line, which typically curves abruptly downwards below the second dorsal fin, then runs straight to the caudal fin.
Teeth
Note the single row of strong, triangular, compressed teeth in each jaw, indicative of its predatory nature.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found in coastal waters from the surface down to about 200 meters (650 feet), but most commonly in the upper 50 meters.
- Ambiente
- Pelagic, inhabiting continental shelves and coastal waters, often near reefs, islands, and estuaries. They prefer clear, warm waters and are frequently found in schools.
- Areale geografico
- Indo-West Pacific: from the Arabian Sea and Persian Gulf eastward to Southeast Asia, including the Philippines, Indonesia, and northern Australia, and northward to Japan. Also found in the Red Sea.

Fatti chiave
Fast Swimmerbehavior
Scomberomorus guttatus is built for speed, with its streamlined body and deeply forked tail, allowing it to pursue and capture fast-moving prey.
Dietary Habitsbehavior
Primarily piscivorous, its diet consists mainly of small schooling fish such as sardines, anchovies, and scads, as well as squid and crustaceans.
Spawning Aggregationsbehavior
This species forms large spawning aggregations in specific coastal areas during reproductive seasons, making them vulnerable to targeted fishing efforts.
No Scales (mostly)interesting
Unlike many fish, Scomberomorus guttatus has a largely scaleless body, except for a small corselet of scales around the pectoral fin and along the lateral line, contributing to its smooth, hydrodynamic profile.
Migratory Patternsbehavior
Known to undertake seasonal migrations, often moving into shallower coastal waters during warmer months for feeding and spawning, and retreating to deeper waters during colder periods.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: No specific venomous spines or dangerous features. However, care should be taken when handling due to its sharp teeth, especially when alive. Standard fish handling precautions apply.
