Biologie     Verklarende woordenlijst (b.v. epibenthic)

Inhabits protected, silty lagoons and estuaries (Ref. 48637). Occurs in pairs, over its burrow beneath rock or rubble; usually hovers a short distance above the bottom. Monogamous (Ref. 52884). Gut contents of a 6.5 cm SL specimen contains mainly fine, unbranched, filamentous algae and harpacticoid copepods, also polychaetes, tanaids, decapod shrimps, amphipods, and nematodes (may have been parasitic).

Estimates based on models

Preferred temperature (Ref. 115969): 25.7 - 29.3, mean 28.2 °C (based on 685 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Kwetsbaarheid (Ref. 59153):  Low vulnerability (20 of 100) .
