The Atlantic Croaker, scientifically known as Micropogonias undulatus, is a species of fish found along the Atlantic coast of North America. It typically inhabits estuaries and coastal waters, preferring sandy or muddy bottoms. This fish is recognized for its distinctive croaking sound, produced by specialized muscles that vibrate its swim bladder. Atlantic Croakers are generally silver in color with a slightly elongated body and can grow up to 20 inches long. They are an important species for both commercial and recreational fishing, often sought after for their mild flavor and firm texture.
