The content of this paper represents part of an investigation into the functional morphology of the dorsal fin-spine of Synodontis zambesensis Peters, 1852, commonly known in this country as the 'squeaker'. The genus Synodontis is generally placed in the family Mochokidae, which includes some of the more specialised catfish. This investigation was conducted by the first author during 1966. Towards the end of the same year Alexander's excellent paper on 'Structure and function in the catfish' (l965) became available, in which the mechanism of the locking dorsal spine of Pimelodus of the family Pimelodidae, a 'fairly primitive catfish' was descriptionbed.
