Definition
A 'croaker' is a type of fish known for making a croaking sound, much like a frog, by vibrating its swim bladder. These fish are commonly found in coastal waters and estuaries, often near muddy or sandy bottoms. Think of them as the underwater vocalists of the fish world 🎤. Their sound isn't as melodious as a songbird, but it's distinctive! They use the sound to communicate, especially during spawning.
