Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Distinguished from other hardyheads by a combination of the following characters (expressed in mean): greatest body depth (mean 4.9), least body depth (mean 10.3) both in SL; eye 3.0 in head; midlateral scale count (mean 31.4). Osteologically diagnosed by the combination of the following: dentition, shape of urohyal, medial wing of pelvic bone and premaxilla. Differs further in lacking ventral processes on fifth ceratobranchial for attachment of pharyngoclavicularis internus muscle (Ref. 26685).
Body shape (shape guide): elongated.

Inhabits warm water (>20°C) of spring-fed pools. Upper temperature tolerance is probably not as high as C. dalhousiensis. Omnivorous. Only co-occurs with C. dalhousiensis in one spring (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±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). 🛈
