Short description Morphology | Morphometrics

Dorsal soft rays (total): 5-7; Anal soft rays: 4 - 5. Metamorphosed females distinguished by the following characteristics: narrow snout, width of ethmoid cartilage and vomer considerably less than the distance between anterolateral tips of the lateral ethmoids and frontals; frontals short, lying posterior to the ethmoid region, dorsal margin convex; frontals separated from prootics; presence of vomerine teeth; large and nearly circular nasal foramina; presence of pterosphenoid; anterior end of illicial trough wider and shallower than the posterior end; well developed sphenotic spines; symphysial cartilage of upper jaw longer than wide; lower jaw with well developed symphysial spine; hyomandibula with double head; well developed quadrate spine, longer than articular spine; deeply notched posterior margin of opercle; long and narrow subopercle, dorsal end long and slender, tapering to a point, ventral end nearly circular; absence of first pharyngobranchial; well developed second pharyngobranchial; second hypobranchial articulates directlywith second basibranchial; caudal fin rays without internal pigmentation; illicium longer than length of escal bulb; pterygiophore of illicium cylindrical throughout length, emerging on snout from between frontal bones, anterior end exposed, posterior end concealed beneath skin; well developed first ray of dorsal fin; dorsal fin rays 5-7; anal fin rays 4-5; short and broad pectoral fin lobe, shorter than longest rays of pectoral fin; pectoral fin rays 16-19; coracoid lacking posteroventral process; simple pelvic bones, expanded distally; skin smooth and naked, without dermal spinules; darkly pigmented skin of caudal peduncle extends well past base of caudal fin (Ref. 86949).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
