Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Found mainly in places where rock and sand form an intermediate biotope. Females which are solitary like males can enter the male's territory found among rocks, and spawn (Ref. 5595). Feed on fish fry (Ref. 267). When feeding, it turns on its side to place its large, laterally compressed jaws into rocky cracks where it captures small fish that are sheltering there (Ref. 6307).
