Teleostei (teleosts) >
Pleuronectiformes (Flatfishes) >
Cynoglossidae (Tonguefishes) > Symphurinae
Etymology: Symphurus: Greek, syn, symphysis = grown together + Greek, oura = tail (Ref. 45335); undecimplerus: Named derived from the Latin 'undecim' meaning eleven, and 'pleurus' meaning many or most, referring to the 11 caudal fin rays and high meristic values when compared to S. melasmatotheca.

Ecology
Marine; demersal; depth range 17 - 56 m (Ref. 9294), usually 20 - 40 m (Ref. 9294). Tropical; 16°N -
Eastern Pacific: Mexico to Peru.

Estimates based on models
Preferred temperature (Ref.
123201): 21.2 - 29, mean 27.2 °C (based on 44 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00507 - 0.02267), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±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.
