Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 11; Afterflossenweichstrahlen: 12 - 13; Wirbelzahl: 35 - 36. The eyes of S. papilliferus (18.4-26.0% HL) are the smallest of the four species of Spintherobolus; the caudal peduncle length is the longest, being 23.8-24.6% SL in males and 21.3-27.0% SL in females; the anal-fin rays of adult males are not expanded in a sagittal plane; segments of anal-fin rays of adult males are not fused; an anterior extension of the proximal end of the lepidotrichia of the anal-fin rays of males is absent.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [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), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
