Actinopteri (ray-finned fishes) > Anguilliformes
(Eels and morays) > Anguillidae
Etymology: Anguilla: Latin, anguilla, .-ae = eel (Ref. 45335). More on author: Kaup.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 51243); depth range - 3000 m (Ref. 86942), usually - m (Ref. ). Tropical; 0°C - ; 1°S - 25°S
Pacific Ocean: Sulawesi, Indonesia to the Society Islands. Also recorded from Pitcairn (Ref. 9828).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 9828); 165.0 cm SL (female); max. published weight: g
Vertebrae: 110 - 114. The only species that can be either variegated or plain-colored. Mottled individuals most closely resemble Anguilla celebensis and A. interioris in having broad, undivided tooth bands, but their ranges do not overlap. Plain-colored individuals most closely resemble A. japonica and A. borneensis, but those species both geographically distant. A. obscura is also plain-colored but has a shorter dorsal fin (Ref. 9828). The skin is grey to yellowish and more or less spotted with brown or black. It can be sometimes uniformly brownish red on the flanks and the back. The belly is white. Young specimens are grey and do not have spots (Ref.48622).
Found in rocky pools, often in coastal streams (Ref. 2847). No separate statistics available (Ref. 9828). The maximum weight (9,000 g) refers to the length (165 cm TL) of a female individual (Ref. 48622).

Estimates based on models
Preferred temperature (Ref. 115969
): 3.7 - 9.6, mean 4.9 °C (based on 415 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00076 (0.00037 - 0.00155), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±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 (72 of 100) .
