Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00351 - 0.01718), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Mức dinh dưỡng (Ref.
69278): 3.7 ±0.6 se; based on size and trophs of closest relatives
