Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Épines anales 0. Mouth greatly enlarged by a backward extension of jaws, gape comprising half or more of preanal length; buccal cavity greatly distensible. Tail attenuated and ending in an expanded, luminous caudal organ. Caudal fin absent; scales absent; lateral line without pores, instead with groups of elevated tubules.

Biologie     Glossaire (ex. epibenthic)

Meso- to abyssopelagic (Ref. 58302) and bathypelagic (Ref. 58426). Adults feed mainly on crustaceans, but also take fishes, cephalopods, and other invertebrates (Ref. 2850, 11041). Oviparous, planktonic eggs hatch into planktonic leptocephalus larvae (Ref. 6719, 35600). Degenerative changes in males and females suggest semelparity (Ref. 35600).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Oviparous (Ref. 35600). Degenerative changes in males and females suggest semelparity (Ref. 35600). Egg cells within each of the gonads have the same developmental stage (monocyclic ovaries) suggesting only one spawning during its lifetime or periodic spawning (Ref. 36055).

Estimates based on models

Preferred temperature (Ref. 115969): 2.3 - 5.5, mean 3.6 °C (based on 890 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  4.1   ±0.56 se; based on food items.
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (Assuming semelparity with tm>10).
Vulnérabilité (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
