Figure 26. Suspensorium and opercular bones of Heterotis niloticus (MCZ 50959, adult, unknown SL) in medial view. A, photograph. B, line drawing. Note the reduced subopercle. The element labelled 'dpl + ecp' has been suggested in the past to be a fusion of the dermopalatine and the ectopterygoid, although no ontogenetic evidence supports this (see Character 30).
