Abstract

The electric organ discharge (EOD) of the mormyrid Pollimyrus isidori is a short pulse with three phases: (1) weak head positive (PI); (2) strong head negative (N); (3) weak head positive (P2). 1. At a stable water conductivity (100 pS/cm), which is near the upper end of the natural range in tropical Africa, there was a statistically significant difference between the sexes only in one of five ...
