Biology     Glossary (e.g. epibenthic)

Occurs at a temperature range of 21.5-29°C (Ref. 2), in all kinds of habitats but is seen mainly in shallow water. Is abundant in shallow vegetated bays. Forms schools. Feeds on phytoplankton, mainly diatoms, and sometimes from the sediment on the sand (Ref. 5595).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.01125 - 0.03539), b=2.98 (2.83 - 3.13), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.24-0.45; tm=3).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
Price category (Ref. 80766):   Unknown.
