Fish aren't known for their sounds, but a new study published in The Journal of Experimental Biology has revealed that when they want to, fish definitely know how to get the point across.
Fish can produce sound by "vibrating their swimbladders," Discovery News reports. By altering the vibrations, fish can create their own Morse Code-like language for communication.
But researcher Loic Kever of the University of Liege found that the pearlfish in French Polynesia's Makemo Island take things a step further. The pearlfish create the vibrations from inside black-lip pearl oyster shells, increasing the volume of their communications.
