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

Typical: 16–26 in, 4–12 lb
Key field mark: The single black spot high on the side plus blue lines under the eye and a pointed anal fin separate mutton from gray snapper; unlike redfish the spot is mid-body (not on the tail base), and unlike red grouper it has a forked tail and canine teeth.

Typical: 10–16 in, 1–3 lb
Quickest tell: Dense small red spots over a pale body, a rounded tail and dark-edged rear fins mark the red hind; mutton snapper is a forked-tailed snapper with canine teeth and a single black spot high on the side.

Both run in Puerto Rico & the U.S. Virgin Islands — that is where telling them apart actually matters.
