More Info
Distribution |
West of Lancelin Island, Western Australia, to off Ashmore Reef, Timor Sea. Elsewhere the species occurs on the continental slope in the east-Indo-west-central Pacific, off Indonesia and the Philippines. Inhabits soft substrates on the mid continental slope at depths of 320–1,460 m, mostly at depths of 900–1,100 m. |
