Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335).
Issue
Last redescription and biology in Le Bail et al. (2000:260). Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig 2; EMBL/GenBank AJ318362 to AJ318364). Biology: Seems to be the unique species of Hypostomus living in brackish waters.
Environment: milieu / climate zone / depth range / distribution range
Écologie
marin; eau douce; saumâtre démersal. Tropical; 26°C - 29°C (Ref. 13614)
South America: Guianan coastal drainages from the Oyapock River to the Demerara River (Ref. 36817). Introduced to Hawaii (Ref. 58302).
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm SL mâle / non sexé; (Ref. 26543)
Facultative air-breathing in the genus (Ref. 126274); A permanent resident of esturial and littoral area (Ref. 90186); in coastal areas and brackish waters of the lower reaches of rivers. Can be caught along the banks with muddy bottom occupied by plants like Laguncularia racemosa, Avicennia germinans and Rhizophora mangle Ref. 35381). Benthic (Ref. 58302). As part of its reproductive behavior, excavates and creates burrows for egg laying (Ref. 82067).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00733 - 0.03589), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
