Short description Morphology | Morphometrics

This species has the following characters: flattened prenarial snout, apparently longer than interorbital width; furrows of upper labial much longer than the lower ones; pectoral fin widely expanding posteriorly, with outer margin a little longer than P1-P2 space; short abdomen, P1-P2 space narrower than preorbital length or anal fin base length; origin of first dorsal-fin just above or slightly anterior to pelvic-fin insertion; 50–64 and 48–68 tooth rows on upper and lower jaws, respectively; teeth with 5 or more cusps, including the anterior ones; egg capsule with no coiled tendrils on anterior and posterior ends, posterior end tapering toward tip; color preserved in alcohol is uniformly pale brownish to light greyish, sometimes light yellowish brown; the dorsal side of body is a little darker than ventral side (Ref. 76943).

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): 3.7 ±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): Low to moderate vulnerability (34 of 100) .

Price category (Ref. 80766): .
