> Gadiformes (Cods) > Macrouridae (Grenadiers or rattails)
Etymology: Hymenocephalus: Named for its transparent membrane-like head covering (‘‘hymen head’’) and fragile nature of head bones (Ref. 100825).

Environment: milieu / climate zone / depth range / distribution range Οικολογία

Θαλασσινό(ά) βενθοπελαγικό; μη μεταναστευτικό(ά); εύρος βάθους 100 - 1400 m (Ref. 3587).   Subtropical; 43°N - 20°S, 97°W - 35°E (Ref. 1371)

Widespread: common in the tropical western Atlantic; Eastern Atlantic: from Portugal to Angola), the Mediterranean. Western Indian Ocean: off southern Somalia to Zanzibar, off Mozambique to Durban, along the Mascarene Ridge and off Maldives (Ref. 98298); including Gulf of Aden and Zanzibar (Ref. 26165).

Length at first maturity / Μέγεθος / Βάρος / Age

Maturity: Lm 2.7, range 3 - 4 cm
Max length : 25.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 3397); μεγ. αναφερόμενη ηλικία: 9 έτη (Ref. 58045)

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Most common at depths less than 500 m (Ref. 1371). Feeds predominantly on pelagic copepods, to a lesser extent on euphausiids and gammarian amphipods, and to a minor extent on shrimps, ostracods, cumaceans, other small crustaceans, and small fish (Ref. 1371). Due to its small size, it is not of significant interest to fisheries (Ref. 1371).
