In particular, we find that the high-pass filter characteristics of Apteornotus afferent response dynamics can serve as a predictive filter for estimating the future position of the prey as the electrosensory image moves across the receptor array. Black Ghost Knifefish Scientific name: The role these FMs have in albfirons is significant, as black ghost knifefish have developed jamming avoidance responseswhich are behavioral responses that avoid the overlapping of EOD frequencies between conspecific individuals to prevent sensory confusion.

Female black ghost knifefish generate EODs at a higher frequency than the males, an FM which can be used for gender recognition.
