Synapomorphies of Pentacerotidae

SA 2. Many exposed tubercles are present on the dorsal and lateral surfaces of the head (including frontal, supraoccipital and pterotic).

Many exposed tubercles are present on the dorsal and lateral surfaces of the head (including frontal, supraoccipital, and pterotic) in pentacerotids. The exposed tubercles are absent on the head in typical percoids (e.g., Gregory, 1933; Imamura, 1996; pers. obs.). The exposed tubercles are present in pentacerotids, and are therefore a synapomorphy.

SA 3. Supraoccipital crest high and stout.

The supraoccipital crest is low and thin in typical percoids (e.g., Gosline, 1985; Yabe, 1985; Sasaki, 1989; Tyler et al., 1989; pers. obs.), while the supraoccipital crest is high and stout in pentacerotids. This condition is a synapomorphy of the family.
