Distribution
Widely distributed in temperate and subtropical parts of most oceans but possibly consisting of a species complex. Western Indian Ocean: Walters Shoal (MNHN 1991-0406). Eastern Indian Ocean: southern Australia. Western Pacific: seamounts in the North Pacific, Japan, Korea, China (and presumably Taiwan and Viet Nam); possibly in New Zealand.
