Etymology: Photonectes: Greek, photos = light + Greek, nekton = swimmer (Ref. 45335).
Eponymy: These are not eponyms but relate to the meanings of ‘margarita’; pearl and daisy. The dragonfish was so-named due to having a “pearl-colored spot above the maxilla”. (Ref. 128868), visit book page.

ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 16 - 18; ຄີກົ້ນຂອງປາ: 19 - 25; ສັດທີ່ມີກະດູກສັນຫຼັງ: 60 - 63. This species of the subgenus Trachinostomias is distinguished by the following characters: vertebrae 60-63 (as an exception, can be reduced to 58); photophores of series IV, 41-45; jaws with uniformly sized teeth; pectoral fin, usually 1 ray P (as an exception, 0 or 2); body with spots of white luminous tissue; mental barbel with a small bulb or even without it, but always with the developed appendages (Ref. 125184).
Mesopelagic species (Ref. 559).
