Etymology: Tripodichthys: Greek, tres, tria = three + Greek, pous = foot + Greek, ichthys = fish; a fish with perches on three fins that form a tripod (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range ? - 15 m (Ref. 9804). Tropical
Western Central Pacific: Australia (including northwestern Australia) and Indonesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9804)
soft rays: 18 - 19. Spiny dorsal-fin membrane very dark between second spine and base of first spine, and often between second and third spines (Ref 9804).
Inhabits sandy and muddy flats in coastal areas. Feeds on benthic invertebrates.
