Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Diagnostic features include the very short abdomen, with interspace between pectoral and pelvic fins base shorter than 3/5 of anal fin base length; pectoral fin tip reaching beyond the midpoint between pectoral and pelvic fins; first dorsal fin smaller in area than the second dorsal; posterior end base (axil) of second dorsal clearly in front of anal fin axil; low anal fin with a long base. Egg capsule very slender; without tendrils, conical posterior end. Claspers without hooks, with posterior margin of exorhipidion forming a free lobe (Ref. 37959). Black, brown or grey (Ref. 11146), without conspicuous markings on fins (Ref. 244).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00301 (-0.14572 - 0.15174), b=3.15 (3.06 - 3.24), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).

Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100) .

Price category (Ref. 80766): .
