Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335);  ypsilychnus: The specific name is a combination of ypsilon, the Greek letter Y, and lychnos, Greek for lamp or light (Ref. 27767). This combination alludes to the Y-shaped posterior organ that is visible through the body wall (Ref. 27767).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 1 - 24 m (Ref. 27767). Tropical

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.3, mean 28.1 °C (based on 1088 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00539 - 0.03078), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±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).
