Nettorhamphos radula, the duckbilled clingfish, is a species of clingfish (family Gobiesocidae) from the Indian Ocean off Western Australia. It is currently the sole member of the genus Nettorhamphos.
Nettorhamphos radula was discovered in a jar at the Western Australian Museum and only scientifically described in 2017. The specimen was caught and brought to the museum in the 1977.[1]
The species resembles other clingfish in being small (about) and having a suction cup on its chest, but differs by its large upper jaw that resembles the bill of a duck and its exceptionally high number of microscopic teeth, between 1,800 and 2,300.[2] [3]
