Genus Philypnodon


Summary:

An endemic Australian genus with at least three species, two known from southern estuaries and freshwater environments.
Body slender, tapering posteriorly; head large, depressed, flattened on top; cheeks broad becoming bulbose in large males; interorbital broad, distance between orbits greater than eye diameter; mouth slightly oblique, small in females and young males, reaching below front to middle of eyes, and reaching to or beyond end of eyes in large males; 1st gill slit open; cheek and opercula without scales; body covered with ctenoid scales, cycloid on belly.

Gill openings restricted, extending forward to below posterior margin of preopercles; sides of belly without vertical bands; pectoral fins each with 15–16 rays; tongue tip rounded to truncate; gill rakers on first arch 11–12; body often mottled ……………………………………………………………………..……..........…Philypnodon macrostomus
