Etymology: Mitsukurina: -ina (L.), belonging to: University of Tokyo zoologist Kakichi Mitsukuri (1858-1909), who placed holotype (provided by Alan Owson, see species) of this “very remarkable shark” in Jordan’s “hands to be identified, figured, and described” (See ETYFish); owstoni: In honor of Alan Owston (1853-1915), English businessman, yachtsman, collector of Asian wildlife, and resident of Yokohama, Japan, who secured holotype from a fisherman (named for Owston at the request of Kakichi Mitsukuri, see genus) (See ETYFish).
Eponymy: Dr Kakichi Mitsukuri (1857–1909) was a Japanese zoologist who first went to the USA (1873) and achieved doctorates from Yale (1879) and from Johns Hopkins University (1883). [...] Alan Owston (1853–1915) was an English businessman who was a collector of Asian wildlife, as well as a yachtsman. [...] (Ref. 128868), visit book page.

Found on outer continental shelves and upper slopes, but rarely in shallow water close inshore (Ref. 247, 43278). Jaws are highly specialized for rapid projection from the head to snap up small animals (Ref. 247). Feeds on jacopever, pelagic octopus and crabs (Ref. 5578). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Probably slow-moving and neutrally buoyant (Ref. 6871). Utilized dried salted (Ref. 247)
