Etymology: Filimanus: Latin, filum = thread + latin, manus = hand (Ref. 45335); similis: From the Latin similis, meaning similar, in reference to the considerable similarity to Filimanus heptadactyla and the other species of Filimanus with shorter pectoral filaments (Ref. 39607).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00308 - 0.01483), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 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).
