A parasite through time: Revisiting Trypanosoma rajae Laveran and Mesnil, 1902 with new molecular and morphological insights from the blood of Rajidae in the western Mediterranean [PDF]
International Journal for Parasitology: Parasites and WildlifeTrypanosomes are blood parasitic protozoa infecting Chordates, including the elasmobranch skates (Rajidae). Amongst, Trypanosoma rajae Laveran and Mesnil, 1902 is a century old parasite, first briefly described from the Mediterranean starry ray Raja ...

Conservation and exploitation status of skate species (Batoidea: Rajidae) in the Balearic Islands, western Mediterranean. [PDF]
PLoS ONEBatoids play key roles in marine ecosystems, yet their slow life history traits make them particularly vulnerable to overexploitation. The Balearic Islands remain a hotspot of batoid diversity, although multiple species could face conservation concerns ...

The combined cartilage growth – calcification patterns in the wing‐fins of Rajidae (Chondrichthyes): A divergent model from endochondral ossification of tetrapods [PDF]
Microscopy Research and Technique, 2022 The relationship between cartilage growth – mineralization patterns were studied in adult Rajidae with X‐ray morphology/morphometry, undecalcified resin‐embedded, heat‐deproteinated histology and scanning electron microscopy. Morphometry of the wing‐fins,

The complete mitochondrial genome of the endemic Iberian pygmy skate Neoraja iberica Stehmann, Séret, Costa, & Baro 2008 (Elasmobranchii, Rajidae) [PDF]
Mitochondrial DNA. Part B. Resources, 2021 Skates, Chondrichthyes fishes from order Rajiformes, are the most species-rich group of all Batoidea. However, their phylogenetic relationships and systematics is still a highly discussed and controversial subject.

Description of a Remarkable New Skate Species of Leucoraja Malm, 1877 (Rajiformes, Rajidae) from the Southwestern Indian Ocean: Introducing 3D Modeling as an Innovative Tool for the Visualization of Clasper Characters [PDF]
Biology (Basel)Simple Summary Skates of the genus Leucoraja Malm, 1877, are small to medium-sized skates that usually have a short, obtusely angled snout. Until now, 14 valid species of this genus have been identified mostly in the Atlantic, but also in the Indian ...
