Gulf Toadfish
Opsanus beta
Gulf toadfish is a stocky, bottom-dwelling toadfish of the Gulf of Mexico and adjacent western Atlantic. It is famous for a loud croak, large flattened head, and venomous dorsal spines; it is usually a bycatch rather than a target species.

Identification points
- Broad, flattened head with a wide mouth
- Mottled brown body with smooth-looking skin and a tapering tail
- Three distinct dark dorsal fins/spiny first dorsal with stout venomous spines
Habitat
Lives on muddy or sandy bottoms, oyster reefs, jetties, docks, seagrass edges, and other structure in shallow coastal bays, estuaries, and nearshore Gulf waters, often hiding in crevices or under debris.
Bait notes
Best taken on the bottom with cut shrimp, pieces of fish, squid, or live shrimp. Small jigs, soft plastics, or scented bottom rigs can also hook them when worked slowly around structure.
Behavior
An ambush predator that sits tight to cover and feeds mainly on small fishes, shrimp, crabs, and worms. It is most active near the bottom and is often caught when anglers fish bait near structure.
Caution
Dorsal spines can be sharp and mildly venomous, so handle carefully. Not a common food fish; if kept, verify local regulations and avoid eating fish from polluted bays due to contamination risk.
Fishing notes
Fish tight to docks, rocks, oysters, and shell bottom with a simple bottom rig and minimal movement. Use light-to-medium tackle; it often bites stubbornly and may swallow bait deeply, so circle hooks help reduce gut-hooking.
