Etymology: Pao: Origin of Pao is from the local name of pufferfishes in Thai and Lao languages, pla pao and pa pao, respectively, with pla and pa meaning fish, and pao meaning purse.; brevirostris: Name from Latin 'palustris', meaning of the marsh or swamp, referring to the main habitats of this species, which lives in marshlands, swamps and floodplains (Ref. 93844).

Known from the middle Mekong basin in Thailand as Tetraodon palustris; lives in marshes and swamps with clear and stagnant water in places with many aquatic plants. From aquarium study, they were observed to spent much of the time hidden among roots and in dense clumps of
submerged plants. Diet in captivity was mainly juvenile fishes, including Nile Tilapia Oreochromis niloticus, and cyprinids, Barbonymus gonionotus, Cirrhinus siamensis and Hypophthalmichthys molitrix (Ref. 93844).

Phylogenetic diversity index (Ref. 82804
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 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.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
