Remarks The specimens of the Mozambican population newly reported here closely overlap with the other populations in meristic and morphometric characters, independent of size (Tab. III). The specimens of the large-sized group (> 110 mm SL) of the South African population are slightly larger than in other populations, which may best explain the occurrence of minor morphometric deviations, as allometric shape changes appear to happen in larger/older specimens, too. The only noteworthy difference between the two size classes is the larger eye size in smaller specimens, a common allometric trend in goatfishes.
