Still in the order Perciformes we come now to three families, Sciaenidae, Pomatomidae, Carangidae, which include a number of sizeable and important fish.
The meagre, the first, may be found as far north as the south coast of England; but the corb and ombrine stay in warmer waters. The sciaenid fish are basically fish of the warm temperate and tropical seas. They are noted for having large otoliths (stones in the ears) and sizeable air bladders which males can cause to resonate, thus producing a noticeable and characteristic noise. The many species which inhabit North American waters are for this reason mostly called croakers and drums or drumfish.
