ABSTRACT: The megamouth shark Megachasma pelagios is a rare, large filter-feeding shark. Little to nothing is known of its sensory biology, particularly in relation to its feeding behaviour. We describe the abundance and distribution of ampullary pores over the head and propose that both the spacing and orientation of electrosensory pores enables M. pelagios to use passive electroreception to maximise feeding efficiency.
