Sebastes diaconus
Marine Life of the Northeast Pacific (MLNEP) notes 4
Likely to be observed in video based on kelp transect observations.
Summary 5
The deacon rockfish has been described as a cryptic species that is difficult to distinguish from the blue rockfish. The deacon rockfish however has more visible stripes in its coloration, whereas the blue rockfish has a 'blotchy' color pattern. As such, prior to the formal classification of the species, the deacon rockfish was referred to as the 'blue-sided rockfish' and the blue rockfish was referred to as the 'blue-blotched rockfish'. The shape of the mouth and front of the face also differs subtly between the two species, with the deacon rockfish exhibiting a longer lower jaw, which results in an underbite. Under dissection, sexually mature female deacon rockfish also have a small pink or cream colored ovary, whereas mature female blue rockfish have a large orange ovary.
The shape of sagittal otoliths has been found to subtly differ between males and females, which may indicate secondary sexual dimorphism.
