Eponymy: One of the ‘heavenly twins’ in Greek mythology (see also Castor). The etymology is not explicit, but apparently so named because the author viewed this species as a ‘twin’ to Cottus gobio. (Ref. 128868), visit book page.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Niveau trophique (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
