Narrow silver body, often with stripes along sides. Spiny 1st dorsal fin, when extended, is similar height to soft rear dorsal fin. This fin is slightly higher than soft dorsal fin in almost identical S. obtusata (Striped Barracuda), which also has a slightly shorter pectoral fin. Both may or may not have yellow tail. Two other very similar small barracudas, S. forsteri (Blackspot Barracuda) and S. helleri (Heller's Barracuda), differ by pelvic fin position further towards tail, but are very difficult to distinguish in field.
