Pantodon
buchholzi,
the African butterfly fish, inhabits an ecological niche at the
water surface in which its visual system must contend with simultaneous
vision in water and through the surface into air. Specific structural
adaptations correlating with the unusual demands of its visual ecology
have been identified in this fish at the lens, retina, and throughout
its visual system. Behaviorally, feeding by this fish is stereotyped
in that it occurs nearly 100% of the time only when target prey
float on or above the water surface, i.e., only from its aerial
visual field. Since neural correlates of stereotyped behavior imply
identified circuits in the nervous system, the feeding behavior
of this fish suggests a unique circuit might be found somewhere
in the aerial visual pathway. Currently, the focus of my lab is
a search for neuronal differences and physiological interactions
within the visual system that serve this behavior.
