Crevalle jacks inhabit shallow coastal waters, estuaries, and occasionally freshwater
They prefer areas with sandy or muddy bottoms and are often found near reefs and seagrass beds
Their diet includes smaller fish, shrimp, and other invertebrates, making them opportunistic predators
Juveniles are commonly found in brackish estuaries and along sandy beaches, moving to deeper waters as they mature
Spawning occurs offshore, typically in warmer months
Eggs are pelagic, floating in the open water until they hatch
Juveniles initially inhabit estuarine and coastal areas before moving to adult habitats
Crevalle jacks form fast-moving schools, although larger individuals may be solitary. They exhibit strong site fidelity, often returning to the same feeding and spawning grounds
