The trumpetfish is a long-bodied fish with an upturned mouth; it often swims vertically while trying to blend with vertical coral, such as sea rods, sea pens, and pipe sponges. It is widespread throughout the tropical waters of western Atlantic Ocean from Florida to Brazil including the Caribbean Sea and the Gulf of Mexico.Trumpetfish occur in waters between 0.5 and 30 meters
deep, and can grow to 40 to 80 cm in length. Trumpetfish swim slowly, sneaking up on unsuspecting prey, or lying
motionless like a floating stick, swaying back and forth with the wave
action of the water. They are adept at camouflaging themselves and often
swim in alignment with other, larger fishes. They feed almost
exclusively on small fish, such as wrasses and Atheriniformes, by sucking them suddenly into their small mouths.
