Etymology: Lavinia: Lavinia, -ae, Latin = daughter of king Latino, married with Aeneas; mythology. More on authors: Baird & Girard.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Temperate; 41°N - 36°N
North America: Sacramento-San Joaquin, Clear Lake, Russian River, and Pajaro-Salinas river drainages in California, USA. Three subspecies were previously recognized: Lavinia exilicauda chi in Clear Lake; Lavinia exilicauda harengus in Pajaro and Salinar River; and Lavinia exilicauda exilicauda in rest of the range.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00445 - 0.02830), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.1 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (43 of 100) .
