About This Creature
An elongated, silvery-grey fish with numerous distinct black spots scattered across the upper body, dorsal fins, and tail fin. Typically measures between 15 to 24 inches in length and weighs 2 to 5 pounds, though can grow larger.
Physical Characteristics
Streamlined body, two dorsal fins with the first spiny and the second soft-rayed, a truncated tail fin, a large mouth with prominent canine-like teeth in the upper jaw, and silvery to greenish-bronze coloration on the back fading to a white belly.
Behavior & Temperament
Forms loose schools, particularly during spawning and winter seasons. Predatory and active primarily during dawn and dusk (crepuscular). Communicates using drumming sounds produced by muscles rubbing against the swim bladder.
Habitat & Diet
Origin Region
Coastal waters of the western Atlantic Ocean and the Gulf of Mexico, ranging from New York down to Florida and around the Gulf coast to Mexico.
Habitat
Inshore marine and estuarine environments, particularly over seagrass beds, sandy bottoms, and salt marshes. Semi-aquatic or fully aquatic.
Diet & Nutrition
Carnivorous. Feeds primarily on smaller fish such as mullet, pinfish, and killifish, as well as crustaceans like shrimp and crabs.
Lifespan & Health
Typically lives up to 8 to 10 years in the wild. Subject to predation by larger fish, dolphins, and ospreys. Females reach sexual maturity around 1 to 2 years of age.
Special Characteristics
Possesses sharp canine teeth used to seize prey. Famous for making a croaking or drumming sound using its swim bladder, particularly during the spawning season.
Ecological Information
Acts as an important mid-to-high-level apex or secondary predator in estuarine food webs, helping regulate populations of smaller forage fish and crustaceans.
