The common skate or blue skate (Dipturus batis[1]) is the largest skate in the world.[2] Historically, it was one of the most abundant skates in the Northeast Atlantic and Mediterranean Sea. Despite its name, today it appears to be absent from much of this range.[3] Where previously abundant, fisheries directly targeted this skate, elsewhere it is caught incidentally as by-catch. Previously assessed as Endangered globally and Critically Endangered in shelf and enclosed seas in the 2000 IUCN Red List, it has been uplisted to Critical Endangered globally in 2006 [4].

[edit] Description

The common skate can grow to 285 cm,[5] making it the largest skate in the world. Overall shape features a pointed snout and rhombic shape, with a row of spines or thorns along the tail.[6] The top surface is generally colored olive-grey to brown, often with a pattern of spots, the underside is lighter blue-grey.[5]
