Short Description
Diagnosis after Compagno, 1984 [517]: Field Marks: A Schroederichthys with moderately slim body, narrow snout, and few large dark and small white spots. Diagnostic Features : Trunk and tail fairly slender in adults but extremely attenuated in young. Snout narrowly rounded; anterior nasal flaps narrow and lobate. Mouth relatively narrow and long, especially in adult males. Colour pattern of 7 or 8 dark brown saddles on grey-brown dorsal surface, also relatively few, scattered large dark and small white spots, the dark spots not bordering the saddles. Adults to at least 70 cm.

Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Sexual dimorphism is evident in dentition of male species (Ref. 49562). Males have longer teeth with fewer cusps than females (Ref. 51093) to make "quot;courtship biting"quot; more effective (Ref. 49562). Feeds on invertebrates and fish (Ref. 43115).
