Etymology: Ceratoscopelus: Greek, keras, -atos = horn + Greek, skopelos = a lantern fish (Ref. 45335). More on author: Lowe.

Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 51 - 1480 m (Ref. 104125). Temperate; - 20°N
Eastern Atlantic: France to Mauritania, including the Mediterranean. Reported from Iceland (Ref. 12462). Western Atlantic: Slope Water and Gulf Streams regions from 50°N to 30°N. Northwest Atlantic: Canada (Ref. 5951).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - ? cm
Max length : 8.1 cm SL male/unsexed; (Ref. 4479)
High-oceanic, schooling, found between 650-700 m during the day and between 51-250 m at night with size stratification with depth (Ref. 4479). Depth range from 460-1082 m1 in the eastern Ionian Sea (Ref. 56504). Juveniles are nyctoepipelagic at the surface. Feeds on copepods and adult or larval forms of other planktonic crustaceans (Ref. 4775).

Estimates based on models
Preferred temperature (Ref. 115969
): 2.7 - 14.2, mean 8.6 °C (based on 494 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00247 - 0.01279), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.38 se; based on food items.
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=2; Fec=2,134; K=1.3-3.65;).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
