The functions of multiple visual signals in a fiddler crab
In many species, it is common for animals to have multiple signals within one channel of communication. Multiple signals may, however, be inefficient if they are redundant in nature. Identifying the functional significance of these multiple signals is therefore important if we are to understand the evolution of such elaborated behaviours. We proposed to identify the roles of movement‐based multiple signals in a model animal system. Male fiddler crabs wave their sexually dimorphic enlarged claw...[Show more]
