Actinopteri (ray-finned fishes) > Carangaria/misc
(Various families in series Carangaria) > Polynemidae
Etymology: Filimanus: Latin, filum = thread + latin, manus = hand (Ref. 45335); heptadactyla: From the Greek hept, meaning seven, and dactyl, finger, in reference to the seven pectoral filaments typically present (Ref. 39607) More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range

Estimates based on models
Preferred temperature (Ref. 115969
): 28.5 - 29.3, mean 28.9 °C (based on 527 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00307 - 0.01559), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.50 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
