Biology     Glossary (e.g. epibenthic)

Occurs in a karst spring, consisting of an artesian resurgence of blue freshwater in a brackish swampy environment with a size and volume varying with the season and with the tidal fluctuation. The bottom of the spring is composed of white sand and limestone boulder with substantial dead tree branches. Syntopic with an unknown species of crayfishes, Cherax sp. (Ref. 91054).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
