Macrouridae (Grenadiers or rattails)
Etymology: Hymenocephalus: Named for its transparent membrane-like head covering (‘‘hymen head’’) and fragile nature of head bones (Ref. 100825).
Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino bentopelágico; no migratorio; rango de profundidad 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).
Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 2.7, range 3 - 4 cm
Max length : 25.0 cm TL macho / no sexado; (Ref. 3397); edad máxima reportada: 9 años (Ref. 58045)
Cross section: compressed.
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).
