Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found in bays and estuaries among submerged vegetation; diurnal (Ref. 4281, 30915). Can tolerate salinities from 1-59 ppt (Ref. 30915). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Length type refers to Height (= from top of coronet to the tip of straightened tail). Breeding in the aquarium is possible (Ref. 130565).

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=0.00447 (0.00177 - 0.01127), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=1; Fec=7).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Preiskategorie (Ref. 80766):   Unknown.
