Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011
Date Assessed: 2003-05-01
Annotations:
Needs updating
Assessor(s): Kyne, P.M. & Cavanagh, R.D.
Reviewer(s): Carlson, J. & Dulvy, N.
Justification:

The Narrowbar Swellshark (Cephaloscyllium zebrum) is known only from two specimens trawled at 444–454 m off Flinders Reef, Queensland (Australia) in the Western Central Pacific. This species may be more widely distributed on the northeastern Australian continental slope than currently known. Nothing is known of its biology. Presently, there is low fishing effort in its area of occurrence. Distribution and status needs to be better defined, and given the lack of available information, an assessment of Data Deficient is appropriate.

History:
2003 Data Deficient (IUCN 2003)
2003 Data Deficient

Habitat and Ecology [top]

Habitat and Ecology:

The Narrowbar Swellshark is recorded from only two specimens from a depth of 444–454 m on the continental slope, but may be more widely distributed on the continental slope off northeastern Australia (Last and White 2008, Last and Stevens 2009). Maximum size is at least 45 cm total length (Last and Stevens 2009). Nothing is known of its biology.

Systems: Marine

Use and Trade [top]

Use and Trade: There is no known use or trade of the Narrowbar Swellshark.

Threats [top]

Major Threat(s): The area where the few known specimens of the Narrowbar Swellshark were collected receives little fishing effort. The species may be naturally rare, but no threats are apparent at present.

Conservation Actions [top]

Conservation Actions: There are no conservation actions in place for the Narrowbar Swellshark. The species' biology and distribution need to be better determined.
