Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Afterflossenstacheln: 0; Afterflossenweichstrahlen: 19 - 22. This species is distinguished with the following characters: short head, nearly as broad as long; blunt snout, well-rounded in lateral profile and dorsally; palatal tooth patches posterior to premaxillary tooth band meet at midline; rounded caudal-fin lobes, of near equal length, fin not deeply forked; short and thick caudal peduncle; underside of body (both head and belly) covered with fine brown specks; anterior gill-rakers on first arch 10-13 (5 + 5); pectoral fin rays 9-12; fatty growth along pectoral fin spines of breeding females not present outside spawning season. Dimorphism present with posterior (humeral) process of cleithrum obvious externally, fan-shaped in females, triangular in males; smooth and shallow dorsomedian cranial depression on exposed skull not reaching supraoccipital process (Ref. 85159).

Carnivorous on benthic invertebrates, primarily annelids (Ref. 4332).

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=0.00427 (0.00167 - 0.01091), b=3.07 (2.85 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.48 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).

Preiskategorie (Ref. 80766): Medium.
