The Reverse Skate (Amblyraja reversa) is known from only a single specimen, collected from 1,500 m depth on the deep slope of the Baluchistan coast off Pakistan in the Arabian Sea. As virtually nothing is known of the species, it cannot be assessed beyond Data Deficient at present. This assessment should be revisited as further information becomes available.

Geographic Range [top]

Range Description:The Reverse Skate is endemic to the Arabian Seas region, where it is known only from the type locality, in the Arabian Sea off the coast of Baluchistan, Pakistan (Lloyd 1906). The species may be more widely distributed than currently known and potentially occurs in India, but this requires confirmation (Akhilesh et al. 2014).
