Thie Sea Robin, a marine fish, measures in at up to 16" long
Sea robins produce sound when out of the water primarily due to the contraction of muscles around their swim bladder, which acts as a resonating chamber. This sound is often a means of communication, helping them to interact with other sea robins or deter potential threats. The sound production can also be a response to stress or discomfort when they are out of their aquatic environment.
