Dataset of the complete mitogenome of the deep-sea sailfin roughshark, Frade, 1929.

Chondrichthyans comprise a diverse group of vertebrate species with extraordinary ecological relevance. Yet, multiple members of this evolutionary lineage are associated with significant extinction risk. The sailfin roughshark is a deep-water benthic shark currently listed as vulnerable due to population declines in parts of its range.

A glimpse into the trophic ecology of deep-water sharks in an important crustacean fishing ground.

Deep-water sharks are among the most vulnerable deep-water taxa because of their extremely conservative life-history strategies (i.e., late maturation, slow growth, and reproductive rates), yet little is known about their biology and ecology.

The complete mitochondrial genome of the endemic Iberian pygmy skate Stehmann, Séret, Costa, & Baro 2008 (Elasmobranchii, Rajidae).

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. The use of complete mitogenome has shown to be a promising tool to fill this gap of knowledge.
