توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 17 - 18; شعاع نرم باله پشتي (کل) : 9 - 12; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 11 - 13; مهره ها: 44. Pelvic fins enormous in juveniles, longer than head length. Pelvic fins fitting into a deep ventral groove at all sizes. Interpelvic process tiny and bifid. No anterior corselet. Swim bladder present with two anterior projections that extend into the back of the skull. The morphological adaptations required for maintaining high brain and retinal temperatures are discussed in Ref. 11221.
Occurs in deep oceanic waters (Ref. 9563), most abundant in waters of 8° to 10°C. Stomach contents of the specimen from north of the Hawaiian Archipelago include onychoteuthids, ommastrephid squid, vertebrae and fin rays from an unidentified fish, bird feathers and parasitic nematodes (Ref. 11006). Taken as longline by-catch by Japanese fishing for Thunnus maccoyii.
