(Tonguefishes) > Symphurinae
Etymology: Symphurus: Greek, syn, symphysis = grown together + Greek, oura = tail (Ref. 45335).
Environment / Climate / Range
Marine; brackish; demersal; depth range 1 - 35 m (Ref. 9294). Tropical, preferred ?; 25°N - 3°S
Eastern Pacific: Mexico to Ecuador. The Seychelles record in Smith & Smith 1963 (Ref. 1623) was based on the type specimen of Symphurus seychellensis which was previously recorded as coming from Seychelles; the correct type locality for the species is northern Peru (Ref. 26282).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00601 - 0.02891), b=3.03 (2.83 - 3.23), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
