Etymology: Amblyrhynchichthys: Greek, amblys = darkness + Greek, rhyngchos = snout + Greek, ichthys = fish (Ref. 45335); micracanthus: From the Greek mikros, meaning small, and akantha, meaning thorn, in reference to the smaller dorsal spine of this species compared to Amblyrhynchichthys micracanthus. More on authors: Ng & Kottelat.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Asia: Mekong, Chao Phraya, Mae Khlong and Tapi river drainages in Indochina.

Maturity: Lm ?  range ? - ? cm
Max length : 19.7 cm SL male/unsexed; (Ref. 55878)
Distinguished from its only congener, Amblyrhynchichthys truncatus, in possessing a more truncate snout (straight vs. gently rounded lateral profile), shorter dorsal spine (15.5-25.7% SL vs. 26.7-29.9), smaller eye when similar-sized individuals of larger than ca. 7 cm SL are compared (28.7-34.9% HL vs. 32.7-36.3) and fewer gill rakers (34-37 vs. 39-40) (Ref. 55878).
Inhabits mainly rivers, with juvenile occasionally entering swamps and flooded fields and feeds mainly on periphyton (Ref. 55878).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00550 - 0.02508), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
