Telling them apart
Red Snapper vs Vermilion Snapper
Look at the anal fin. A red snapper's is sharply pointed; a vermilion's is rounded. Red snapper also have a red iris and a much bigger mouth, and a far deeper body.

Why the difference matters
Red snapper is one of the most tightly regulated fisheries in the Gulf, with short seasons, a small bag and a real minimum size, while vermilion are frequently open when red snapper are not. Both come off the same piece of bottom on the same drop, so the anal fin is the check that keeps a legal box legal.
Size limits, bag limits, slot limits and seasons are set by your state wildlife agency — and for many offshore and migratory species by federal regulators — and on many waters they differ from the statewide rule. They also change between seasons. Check the current regulations for the exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
