Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 16; Rückenflossenweichstrahlen (insgesamt) : 10 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 8. Diagnosis: lower pharyngeal jaw robust and of moderate size, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth (Ref. 26738, 81260). Mouth not squared or obtuse (Ref. 81260). Ventral margin of lower lip smooth; ratio of lower jaw length to lower jaw width < 1; oral jaw teeth slender, movably implanted with spatulate crowns (Ref. 26738, 81260). 11-13 gill rakers on first arch (Ref. 26738).

Feeds primarily upon plants (especially algae), diatoms and insects (Ref. 52307). Pair-bonding, open (Ref. 52307)substrate brooder (Ref. 52307, 81260), with both parents guarding the brood (Ref. 52307).

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=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.1 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).

Coptodon thysi (Stiassny, Schliewen & Dominey, 1992)
