Two fish anglers routinely mix up. Here is what actually separates them — and when and where you are likely to meet each.

Typical: 11–17 in, 1–3 lb
Quickest tell: The long single spiny dorsal with rows of white spots, plus the trailing top tail-ray filament (and bluish nuchal hump) on adults, separate it from the blunt rubbery-lipped tautog and the deeper-bodied, smaller-mouthed scup.

Typical: 8–14 in, 0.5–2 lb
Quickest tell: The deep silvery oval body with a tiny blunt mouth and no fangs or incisors marks a scup; black sea bass is darker, longer-bodied, and shows white-spotted fin rows, while sheepshead wears bold black bars and protruding front teeth.

Both run in Mid-Atlantic, Northeast — that is where telling them apart actually matters.
