(Mackerels) > Nomeidae
Etymology: Cubiceps: Latin, cubus = cube + Latin, ceps = head (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range - 140 m (Ref. 54802), usually - m (Ref. ). Subtropical; 0°C - ; 40°N - 35°S
Probably circumglobal in tropical and temperate seas. Reported from the Mediterranean (Ref. 11228).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 101 cm TL male/unsexed; (Ref. 5951)
Oceanic, epipelagic or mesopelagic in tropical waters. Feeds mainly on salps (Ref. 33689). Occurs near the surface at night but depth at daytime is not known. Excellent food fish.

Estimates based on models
Preferred temperature (Ref. 115969
): 16.4 - 26.4, mean 21.9 °C (based on 848 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00411 - 0.02324), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.0 se; based on diet studies.
Resilience (Ref. 120179
