Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin récifal; profondeur 2 - 25 m (Ref. 48637). Tropical; 31°N - 31°S, 31°E - 169°W
Indo-West Pacific: Persian Gulf (Ref.80050); Red Sea to Samoa, north to the Ryukyu Islands, south to the Great Barrier Reef. The exact range is uncertain because of confusion of this species with Sphyraena obtusata (Ref. 9768). Lessepsian migrant to the Mediterranean (Ref. 50345).
Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm 28.0  range ? - ? cm
Max length : 60.0 cm TL mâle / non sexé; (Ref. 9768); common length : 40.0 cm TL mâle / non sexé; (Ref. 9768); âge max. reporté: 99 années (Ref. 116929)

Body with two brown or brownish yellow longitudinal stripes which may disappear in old specimens; caudal fin yellowish (Ref. 9768). S. flavicauda is more elongate than S. obtusata and differs in dorsal fin height pectoral fin length (Ref. 37816).
Body shape (shape guide): elongated.
Inhabits lagoon and sheltered seaward reefs (Ref. 9710); also found in bays (Ref. 9768). Often schools on coastal reefs (Ref. 48637).
