Macrourids like this one are an incredibly common and diverse family of deep-sea fish with more than 200 species. They have a long, tapering tail that got them the nickname “rattail,” though due to commercial fishing, they have been renamed “grenadiers.” This rattail was seen on Dive 14 at Explorer Ridge Deep at a depth of 2,228 meters on July 1, 2016.
