Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011
Date Assessed: 2010-01-20
Assessor(s): Kyne, P.M.
Reviewer(s): Carlson, J. & Dulvy, N.
Justification:

Cook’s Swellshark (Cephaloscyllium cooki) is a small (to 30 cm total length), poorly known deepwater catshark, with a restricted distribution off northern Australia and eastern Indonesia. This species occurs on the upper continental slope at depths of 225–300 m. Nothing is known of its biology or capture in fisheries and it is known from only a handful of specimens. The species’ status needs to be better defined, and given the lack of available information, an assessment of Data Deficient is appropriate.

Geographic Range [top]

Range Description:
