Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Eggs have horn-like projections on the shell [17086]. Small individuals preyed on benthic gammarid amphipods and isopods. In larger skates, >50 cm D, Patagonotothen ramsayi, other fish species and Loligo gahi became increasingly important (Ref. 54177).
