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

Typical: 12–18 in, 1–3 lb
Quickest tell: Black blotches on the spiny dorsal-fin membrane plus a rounded/slanted anal-fin margin ID Black Rockfish, versus Widow's clear fin membranes and straighter anal-fin margin.

Typical: 14–24 in, 2–6 lb
Quickest tell: Run a finger along the lateral line: Canary shows a clear light-gray stripe right at the lateral line with 3 orange head bars, while Vermilion is more uniformly red with black fin edges; neither has Yelloweye's yellow eye or raspy eye ridges.
