Abstract
Understanding elasmobranch reproductive biology is necessary for species conservation. Multiple paternity (MP) has been reported for elasmobranchs, and this study investigates the reproductive aspects and mating system (paternity genetic analyses) for Squalus albicaudus. Thirteen pregnant females were analysed concerning reproductive parameters, and the mating system was assessed for nine females and their litters. The study found a mean fecundity of 2.84 pups per litter without correlation between total female length and the number of embryos per litter. One litter showed evidence of MP, indicating the presence of polyandrous behaviour of the species.
