Anodontiglanis dahli (English Toothless Catfish ) is a freshwater catfish from the coral catfish family that occurs in northern Australia. The species is the only member of the genus Anodontiglanis .
features
This species of coral catfish is usually eight inches long (up to a maximum of four inches) and is grayish or brown in color and has some vertical lines of pale spots on the sides. The front dorsal fin is narrow and long and has a hard, sharp fin ray and six soft rays. The second dorsal fin and the anal fin are fused with the caudal fin and consist of 175 to 180 fin rays, the pectoral fins have a sharp hard ray and eleven soft rays. Except for a few inconspicuous teeth on the ploughshare (vomer), the species is toothless.
The dorsal part of the caudal fin begins far in front at the level of the pelvic fins, in contrast to the approach that begins further back in all other Australian coral catfish. In addition, the front dorsal fin is relatively narrow but long compared to the other species.
Distribution and way of life
The species occurs sporadically in freshwater in northern Australia, such as in the Fitzroy River (King Sound) , in most of the coastal rivers of the Northern Territory as well as in the Mitchell River (Gulf of Carpentaria) and in the Archer River on the west side of the Cape York Peninsula .
The fish are more solitary and prefer sandy bottom near dead wood in clear rivers. There they search for food with their mouths in the sandy soil. They feed on aquatic insect larvae, detritus , mollusks, and shrimp.
