Dinematichthyidae (Viviparous brotula)
Etymology: Alionematichthys: Name from Latin alius meaning the other or different, and nematichthys, the stem of the genus name Dinematichthys, to which this genus is most similar.

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
