Communication and Perception
There is limited information available on the communication among cod. Atlantic cod are hypothesized to communicate through the production of sound via drumming muscles. Sound production is correlated with mate selection during spawning season. It is hypothesized that the degree to which males are able to produce acoustic sound is positively associated with the overall fitness of the males, with those having larger drumming muscles producing greater sound waves and out-competing others.
