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.

Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino pelagic-oceanic; oceanodromo (Ref. 51243); distribuzione batimetrica 0 - 805 m (Ref. 13608), usually 450 - 500 m (Ref. 4775). Subtropical; 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).

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 14 - 15; Spine anali: 0; Raggi anali molli: 14 - 15.
Body shape (shape guide): fusiform / normal.
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).
