Blue skate
species of fish
The blue skate (Dipturus batis), also known as the grey skate, blue-grey skate, and common skate, is a species of cartilaginous fish, a ray, belonging to the family Rajidae, the skates. It was formerly considered to be conspecific with the flapper skate (D. intermedius), the combined taxon being known as the common skate. Historically, it was one of the most abundant skates in the northeast Atlantic Ocean and the Mediterranean Sea. Despite its name, today it appears to be absent from much of this range. Where previously abundant, fisheries directly targeted this skate and elsewhere it is caught incidentally as bycatch. The former species was uplisted to critically endangered on the IUCN Red List in 2006 and it is protected within the EU.
Research published in 2009 and 2010 showed that the common skate should be split into two, the smaller southern D. cf. flossada (blue skate), and the larger northern D. cf. intermedius (flapper skate). Under this taxonomic arrangement, the name D. batis is recommended to be discarded. Currently, the scientific name D. batis (with flossada as a synonym) is retained for the blue skate and D. intermedius for the flapper skate.
Begin with the source’s own compact description: “Blue skate” is species of fish. The dossier treats that line as a proposition to test through Blue, skate and species, not as a finished interpretation.
Why this record matters
The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 23, 2026. The linked authority identifier is Q1421947. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006, 2009 and 2010.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
