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: 14–20 in, 2–5 lb
Quickest tell: The blunt rubbery-lipped head, thick leathery skin, and uniform blotchy dark coloring (no white-spotted fin rows, no trailing tail filament) separate tautog from the lighter, spinier black sea bass.

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