Description
Adults virtually identical in appearance to B. diana (Diana's Pigfish) but recently described as a separate species. Best distinguished on basis of location (B. dictynna Pacific Ocean only), although juveniles have slightly different spot patterns on the head. B. diana has more light spots on the snout and more distinct spots behind the eye, while many of the spots behind the eye are fused to form elongated markings in this species.
