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

Typical: 14–22 in, 2–8 lb
Quickest tell: The single fleshy flap on the snout, a fully scaleless body, and the absence of big canine teeth distinguish cabezon from the toothy lingcod and from the smaller sculpins.

Typical: 24–36 in, 5–20 lb
Quickest tell: Big fanged canine teeth, an elongate body, and a long notched dorsal separate lingcod from the toothless-jawed, broad-headed cabezon.
Both run in Northern California, Pacific Northwest — that is where telling them apart actually matters.
