This is the first description of vocalisations produced by the mormyrid species Petrocephalus catostoma from the Upper Zambezi River whilst defending a territory. Agonistic behavioural displays of a dominant male towards a conspecific, such as mutual circling or short attacks, were accompanied by characteristic tonal sounds, termed hoots. The mean hoot duration (43 +/- SD 1.8 ms) was longer, and the fundamental frequency (H1, 180 +/- SD 4.7 Hz) lower, than in the closely related species Petrocephalus ballayi. P. catostoma vocalised hoots only during intraspecific agonistic interactions, especially those accompanying territorial conflict.
