Biologie     Verklarende woordenlijst (b.v. epibenthic)

Adults occur in estuaries and freshwater habitats, frequently where mangrove are abundant. Presence of toxic buccal glands associated with the grooved canines. This is avoided by predators which even reject it unharmed if they try to ingest it. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Both fang and venom gland is present (Ref. 57406).

Estimates based on models

Preferred temperature (Ref. 115969): 28.2 - 29.4, mean 28.8 °C (based on 1032 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00255 - 0.01239), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 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 (17 of 100) .
