Fun Facts about the Quillback Rockfish

      Quillback rockfish have internal fertilization. The embryos develop inside the mother and she gives birth to live young.

      The dorsal fin and spines are a distinctive feature of this fish. The spines are deeply incised and are white or light yellow but can have dark brown or black saddles on them. 

      Quillbacks have also been transported outside of their home range and were found to return to that same location, demonstrating site fidelity.
