Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 16-18; Anal spines : 0; Anal soft rays : 3.

Biology     Glossary (e.g. 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 ):  PD 50 = 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 Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (tm=1; Fec=7). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
