The fish lives in deep water and is bluish black along its upper sides and whitish underneath.
Blueback (SS-581) earned two battle stars for her Vietnam War service.
Blueback appeared in an episode of the 1970s television series Hawaii Five-O. Blueback also appeared in the 1990 movie The Hunt for Red October,
