Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335).
Eponymy: Auguste Henri André Duméril (1812–1870), was a physician and zoologist like his father (see next entry) and followed much in his father’s footsteps. [...] (Ref. 128868), visit book page.

生態學
海洋; 海洋洄游的 (Ref. 51243); 深度上下限 0 - 805 m (Ref. 13608), usually 450 - 500 m (Ref. 4775). 亞熱帶的; 51°N - 40°S
Eastern Atlantic: Canary Islands (Ref. 6808), 20°N (inshore from 29°N) to about 10°S west of 0°, with disjunct distribution between 14°N and 8°N, but to 23°S east of 0°. Isolates north to off south-west Ireland (Ref. 4775). Western Atlantic: tropical areas but with expatriate extensions to 51°N and 45°S in western boundary currents [(apparently absent over a minimum region off Brazil) according to Ref. 4479 or 4775] (Ref. 4479, 4775). Very rare or absent in the Indo-Pacific.
Tropical Indian and Atlantic; east coast of South America (Ref. 47377).

熱帶印度洋與大西洋; 南美洲的東海岸.(參考文獻 47377)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 5.2 range ? - ? cm
Max length : 9.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 40727); 最大年齡: 1.00 年 (Ref. 4882)
背棘 (總數) : 0; 背的軟條 (總數) : 14 - 15; 臀棘: 0; 臀鰭軟條: 14 - 15.
High-oceanic and mesopelagic populations are found between 225-750 m during the day (maximum abundance at 450-500 m) and is nyctoepipelagic at surface down to 125 m at night (Ref. 4479). Pseudoceanic and pelagic populations are found in the upper 50 m at night (Ref. 4066). Feeding is acyclic in northwest Africa (Ref. 9198).
高度大洋性與海洋中層帶的魚種族群在 225-750 公尺之間被發現在白天期間 (最大的豐度在 450-500 公尺) 而且在表面是夜浮性的向下至 125 公尺在晚上.(參考文獻 4479) 偽洋性與大洋性的族群被發現於上面的 50 公尺在晚上。 (參考文獻 4066) 進食在非洲西北部是非循環式的。 (參考文獻 9198)
