snappers

Snappers are a common name used for various species of fish in the family Lutjanidae, a group of warm-water marine predators often associated with reefs and coastal environments. Most species are targeted by commercial and recreational fisheries because they are edible and form important components of reef ecosystems. Well-known examples include the red snapper (Lutjanus campechanus), the mutton snapper (Lutjanus analis), the lane snapper (Lutjanus synagris), and the yellowtail snapper (Ocyurus chrysurus). These fishes typically have compressed bodies, a series of spines on the dorsal fin, and coloration that can range from silver to pinkish to olive, depending on species and environment. They occur primarily in the western Atlantic Ocean and Gulf of Mexico, with associated Caribbean habitats and adjacent coastal waters.

Ecology and life history vary by species but share several traits: they are ambush and pursuit predators that feed on fish, crustaceans, and occasionally mollusks; many are relatively long-lived and attain sexual maturity slowly, which makes them vulnerable to overfishing. Management in many regions includes size limits to protect juveniles, bag limits, seasonal closures, and quotas; some populations have recovered after strict controls, while others remain under pressure due to habitat loss and bycatch.

Snapping turtles, by contrast, refer to large freshwater turtles known for a powerful bite. The common snapping turtle (Chelydra serpentina) is native to North America and thrives in rivers, lakes, and wetlands. The larger alligator snapping turtle (Macrochelys temminckii) inhabits southern U.S. rivers and swamps and is among the longest-lived freshwater turtles. Snapping turtles are carnivorous, feeding on amphibians, fish, invertebrates, and carrion. They face threats from habitat destruction, pollution, road mortality during migrations, and overharvesting in some areas; several jurisdictions protect populations or regulate collection.
