Etymology: Paraliparis: Greek, para = the side of + Greek, liparis = fat (Ref. 45335); epacrognathus: From the Greek epakros, pointed at the end, and gnathos, jaw, to denote the sharply angled lower jaw symphysis (Ref. 90026). More on author: Stein.

Morphology | Morphometrics
V 67, D 60, A 51, C 7, P 21. Lower jaw forming a sharp angle at symphysis; chin pores at symphyseal knob. Teeth primarily uniserial, irregularly biserial near symphysis. Upper and lower jaws long, 53% HL. Pectoral fin notch rays present as rudiments reduced to bases only. Radials 4 (3+1), R1 and R3 smaller than R2 and R4. Coracoid notch absent (Ref. 90026).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00219 - 0.00998), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (31 of 100) .
