The southern African skate fauna is best known off the temperate west coast of South Africa from the intertidal to approximately 1,200 meters, but poorly

These two factors are suggestive of a communicative role for the electric organ in skates, a role that has been demonstrated in similarly weakly ele

Using logistic regression, it was determined that TL at 50% maturity of males was 475 mm TL and of females 520 mm TL. This estimation agrees with the morphological parameters measured.
