Etymology: Anguilla: Latin, anguilla, .-ae = eel (Ref. 45335); luzonensis: Named for P.C. Huang, for guiding determination of the first complete sequence of a fish mitochondrial genome.
Most probably the same as Anguilla huangi Teng, Lin & Tzeng, 2009, priority remaining to establish.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 83381). Tropical
Philippines: upper reaches of the Pinacanauan River system, a tributary of the Cagayan River in northern Luzon Island, Philippines.

Morphology | Morphometrics
Vertebrae: 103 - 106. An anguillid eel with variegated color marking with broad maxillary bands of teeth that is classified into the first group of Anguilla. Predorsal-fin length 28.6-33.1% of TL; preanal length 39.6-44.8% of TL; preanal length without head length (trunk length) 26.4-31.3% of TL; distance between the verticals through the anus and origin of the dorsal fin 9.3-13.9% of TL; LG 35.5-46.9% of HL; TV 103-107; and AV 40-42.
The body is elongate. Body color when fresh was mottled with yellow, olive green, and dark brown or black, but it changed after formalin fixation, with the coloration being more dark or obscured. HL 10.8-15.1% of TL, predorsal lengths without head length 15.5-19.7% of TL. Distance from perpendicular through eye-center on the margin of upper jaw to angle of gape 29.9-41.8% of LG. Caudal vertebrae 61-66. (Ref. 83381).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00079 (0.00039 - 0.00163), b=3.16 (2.99 - 3.33), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100) .
