Biology     Glossary (e.g. epibenthic)

This species prefers to hide in weeds if present, floating or not, often high up in water column, sometimes even at the surface under a water lily leaf in bright sunlight; also found on rocky bottom, hiding in crevices and holes (Ref. 94890). It will often not struggle in weeds brought to shore, so as not to raise attention (Ref. 94890).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
