Teleostei (teleosts) > Acropomatiformes (Oceanic basses) > Hemerocoetidae (Indo-Pacific duckbills)
Etymology: Pteropsaron: Greek, pteron = wing, fin + Greek, psaron = grey, with different colours (Ref. 45335); longipinnis: The name refers to the elongate dorsal and pelvic fins,especially the latter which defines it from the nearest relative P. springeri..

Estimates based on models

Preferred temperature (Ref. 123201): 24.4 - 26.1, mean 25.9 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 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).
