Our treatment of perciforms ends appropriately with anenigmatic group whose exact placement remains something of a puzzle. In many earlier treatments, the caproid boarfishes were thought to be preperciforms, most closely allied with the zeiform dories, which they resemble. Somerecent analyses retain that analysis (e.g., Tyler et al. 2003)whereas others consider them an advanced perciform, adecision Nelson (2006) follows but with uncertainty. These are medium-sized (to 30 cm), reddish, deep-bodied, rhomboid,schooling fishes of moderate depths (50–600 m).
