Is behavioral lateralization in fish related to morphological asymmetry?
We address this question in a livebearing fish species that shows a unique form of morphological asymmetry. The species Xenophallus umbratilis exhibits a mating morphology where the male gonopodium—a structure used to inseminate females—terminates with either a dextral (right-handed) or sinistral (left-handed) corkscrew (Figure 1). We think that this might be related to a phenomenon in which individuals show a lateral bias in eye use to approach stimuli, a form of behavioral lateralization.
