Etymology: Astronesthes: Greek, astra = ray + Greek, esthes, -es = suit, something used to wrap (Ref. 45335).
Environment: milieu / climate zone / 深さの範囲 / distribution range
生態学
海 深海浮遊性; 深さの範囲 50 - 2230 m (Ref. 58302). Deep-water; 25°N - 37°S, 15°E - 154°W
Indo-Pacific: Its range seems to represent the equatorial distributional pattern; it expands southwards in the western parts of the Pacific (including the Philippine Sea, Ref. 41299), and Indian oceans; absent in the eastern part. Atlantic Ocean: Present in a small portion near southern Africa.

背面の脊椎 (合計) : 0; 背鰭 (合計) : 14 - 17; 肛門の骨: 0; 臀鰭: 12 - 16; 脊つい: 43 - 46. Last photophore of VAL series behind origin of anal and last photophore of VAV series. Aggregation of luminous tissue on head, when fully developed fish > 10 cm SL, forming transverse bar across gill cover; longitudinally oriented aggregations of luminous tubercle-like spots on body behind head and above pelvic fins. In immature fish < 6 cm SL, chin barbel fully developed, longer than head, its swollen tip forming elongate thickened rod with two flattened distal lobes (Ref. 27676).
Body shape (shape guide): elongated.
Epi- and mesopelagic, with fishing depths to 4000 m (Ref. 58302). Found on the continental slope (Ref. 75154).
