Mugilidae (grey mullet; subclass Actinopterygii, order Perciformes)
A family of marine and brackish-water fish, which occasionally enter rivers. A mullet has a fairly thick, solid body with rather large scales, the mouth bearing rows of fine teeth. The pelvic fins
are located between the pectoral
and first dorsal fins
. The two widely separated dorsal fins are characteristic. Often congregating in large schools, most species feed on plankton, algae, or detritus. They are very tolerant of low salinity: some species, including Myxus
(freshwater mullet) of eastern Australia
, are freshwater inhabitants. Mugli cephalus
(striped, or common mullet), 65 cm, is an example of the commercially important food fish in the family. There are about 70 species, distributed world-wide in tropical and temperate waters.
