Abnormal hermaphroditism in the multispine skate Bathyraja multispinis (Chondrichthyes, Rajidae)
Journal of Fish Biology, 2007 A hermaphroditic individual of the multispine skate, Bathyraja multispinis, caught on the Argentinean continental shelf, is described. This is the first record of hermaphroditism in the genus Bathyraja and one of the very few hermaphroditic specimens reported in the Rajidae.

Reproductive biology of the southern thorny skate Amblyraja doellojuradoi (Chondrichthyes, Rajidae)
Journal of Fish Biology, 2016 The total lengths (LT) of 193 males (209–556 mm) and 130 females (275–515 mm) of Amblyraja doellojuradoi, a commercial by‐catch species on the Argentinean continental shelf, which are increasingly retained, were analysed. No sexual dimorphism was observed in the LT at which 50% of individuals were sexually mature; males matured at 448 mm and females at
