Etymology: Rhynchobatus: Greek, rhingchos = snout + Greek, batis, -idos = a sting ray (Raja sp.) (Ref. 45335).
Eponymy: Hans Julius Lübbert (1870–1951) studied politics and law at universities in Kiel and Rome, but caught severe malaria and had to change course. [...] (Ref. 128868), visit book page.

Benthic (Ref. 114953). Occurs in shallow coastal waters, more or less stationary. Ovoviviparous (Ref. 50449). Adults feed mainly on small bony fishes and invertebrates. Females have litters of 2-5 pups. Maturity size unknown but born at 79-85 cm TL (Ref. 114953).
Life cycle and mating behavior
Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven
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).
