Methods for the Taxonomic Study and Description of Skates (Rajidae)

Copeia, 1968
Recent studies show the need for defined methods of systematically studying and describing skates. Disc width is proposed as the basis for proportional measurements of various parts of the disc, tail, fins, and head; of distances between certain spines; and of dimensions of ocellus.

Step by step: the unprecedented evolutionary history of family Rajidae

2019
Among skates, Rajidae represents one of the most enigmatic family of cartilaginous fish whose bio- ecological traits contributed to an extraordinary evolutionary success in terms of species richness and endemism. Past and present taxonomic conflicts and species misidentifications are linked to their extraordinary level of morphological stasis.
