coral reefs.

(14°S), probably occurs in our area.

Genus Pomacanthus Lacepede, 1803
Preorbital mostly without spines, its lower rear edge not
free; interoperc1e and suboperc1e smooth; anterior nostril
the larger; suprac1eithrum elongated, inconspicuous. Two
predorsal bones. Juveniles blue or black with lighter narrow
and wide bands, mostly completely different in colour from
adults. Pomacanthops Smith, 1955 is a synonym. About 22
species, 5 reach our area. P. maculosus (Forsskal, 1775) is
known from Porto Amelia and probably also occurs in our
area.
