[2] In 1829 the French zoologist Georges Cuvier described Cottus claviger, also from Kamchatka, and in 1839 the English zoologist William Swainson proposed a new monospecific genus for Cuvier's species which he called Enophrys.

[3] Later Cuvier's C. claviger was found to be a synonym of Pallas's C, diceraus but it is the type species of the genus Enophrys.

[2][3] The specific name diceraus means "two-horned" a reference to the preopercular spines, one on each side of the head.

[1] The large lateral line scales are plate like and have 1 or 2 keels and a rough rera edge.

[5] Enophrys diceraus eats benthic invertebrates, especially crustaceans and molluscs, although adults eat brittlestars too,[5][6] The adults move into shallow water to spawn, the juvenile settle at lengths between 13 and 24 mm (0.51 and 0.94 in) and they become sexually mature at 18 cm (7.1 in).
