Description of the clasper of the Southern Thorny Skate Amblyraja doellojuradoi (Pozzi, 1935) (Chondrichthyes: Rajidae)

Gabriela Delpiani, Daniel E. Figueroa and Ezequiel Mabragaña


This work constitutes the first description of the clasper of Amblyraja doellojuradoi. The characterization was based on both external morphology and the composition of the internal cartilages. A comparison based on these structures with other species of the genus is provided. Considering all of the cartilages, the basal and terminal series of A. doellojuradoi are more similar in shape and disposition to the equivalent series in A. radiata than to A. hyperborea. However, marked differences in clasper cartilages permit A. doellojuradoi to be distinguished from these congeners.
