Greater Amberjack
Seriola dumerili
Key differences: S. dumerili typically has a darker, more pronounced diagonal stripe from the snout to the first dorsal fin, which often fades or becomes indistinct in larger adults. Its body is generally deeper and less elongated than S. lalandi. The yellow lateral stripe is usually absent or much less prominent in S. dumerili, and its fins are typically darker, not bright yellow.

Seriola rivoliana
Key differences: S. rivoliana has a much deeper body profile, appearing more compressed laterally. Its second dorsal and anal fins are notably taller and more falcate than those of S. lalandi. The yellow lateral stripe is usually absent or very faint, and its fins are typically darker.
California Yellowtail
Seriola dorsalis
Key differences: Historically, S. dorsalis was considered a subspecies of S. lalandi. Recent genetic studies have elevated it to a distinct species. Morphologically, it is very similar to S. lalandi, but typically has a slightly deeper body and a more pronounced, often darker, yellow stripe. Distinguishing between the two often requires genetic analysis or precise meristic counts, though their geographic ranges largely overlap in the Eastern Pacific.
