''Siphonognathus'' is a genus of ray-finned fishes, weed whitings in the Family (biology), family Odacidae which are endemism, endemic to Southern Australian coastal waters. These fish are characterized by their extremely elongate bodies and live primarily in seagrass beds.

Species

There are currently six recognized species in this genus: * ''Siphonognathus argyrophanes'' John Richardson (naturalist), J. Richardson, 1858 (Tubemouth) * ''Siphonognathus attenuatus'' (James Douglas Ogilby, J. D. Ogilby, 1897) (Slender weed whiting) * ''Siphonognathus beddomei'' (Robert Mackenzie Johnston, R. M. Johnston, 1885) (Pencil weed whiting) * ''Siphonognathus caninis'' (John K. Scott, J. K. Scott, 1976) (Sharpnose weed whiting) * ''Siphonognathus radiatus'' (Jean René Constant Quoy, Quoy & Joseph Paul Gaimard, Gaimard, 1834) (Long-rayed weed whiting) * ''Siphonognathus tanyourus'' Martin Fellows Gomon, M. F. Gomon & John Richard Paxton, Paxton, 1986 (Longtail weed whiting) Although Fishbase places all six of these species in the genus ''Siphonognathus'', the Catalog of Fishes places ''S. attentuatus'', ''S. beddomei'', ''S. radiatus'' and ''S. tanyourus'' in the separate genus ''Sheardichthys'' and places ''S. caninis'' on the Monotypy, monospecific genus ''Parodax'', leaving ''Siphonognathus'' as a monospecific genus containing only the tubemouth (''S. argyrophanes'').
