Eponymy: In Roman mythology, Castor and his brother Pollux were the heavenly twins. However, in Latin Castor also means ‘beaver’, and the mormyrid was so named because of the teeth which protrude from its lower jaw, like a beaver’s incisors. (Ref. 128868), visit book page.

Estimates based on models
Preferred temperature (Ref.
123201): 16.7 - 25.4, mean 21.2 °C (based on 59 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00620 - 0.02676), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
