Classification / Names Nomi Comuni | Sinonimi | Catalog of Fishes(Genere, Specie) | ITIS | CoL | WoRMS | Cloffa

> 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 Ecologia

marino benthopelagico; non migratori; distribuzione batimetrica 100 - 1400 m (Ref. 3587). Subtropical; 43°N - 20°S, 97°W - 35°E (Ref. 1371)

Distribuzione Stati | Aree FAO | Ecosystems | Presenze | Point map | Introduzioni | Faunafri

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 / Size / Peso / Age

Maturity: Lm 2.7, range 3 - 4 cm
Max length : 25.0 cm TL maschio/sesso non determinato; (Ref. 3397); Età massima riportata: 9 anni (Ref. 58045)

Biologia     Glossario (es. 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).

Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 15.9, mean 12.6 °C (based on 338 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00162 (0.00101 - 0.00260), b=3.05 (2.91 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.0 se; based on diet studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.18; tmax=9).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
