وصف مختصر الوصف الخارجي | قياسات المظهر الخارجي

This species is distinguished by the following set of characters: snout obtusely wedge shaped, angle ca. 52-57°; preoral length 17.4-17.9% TL, prespiracular length 19.3-19.5%; interdorsal space 16.7-17.9%; total pectoral-fn radials 54-56; total free vertebral centra 136-144; tooth rows on upper jaw ca. 54-66; no spines on snout; outer fold on posterior margin of spiracle is more pronounced than inner fold; pre-first dorsal-fin length 46.4-48.6%; apex of dorsal fins bluntly rounded; origin of first dorsal fn about level with the pelvic-fin origin; middle of pectoral disc with a spiracle-sized black blotch followed by a single white spot (rarely absent) posterodorsally; distal region of pectoral disc to mid-dorsal area without distinct white spots; a single blotch below the eye is usually absent; anterior half of undersurface covered with a rounded black blotch; near the snout tip, a pair of small distinct black spots (Ref. 123186).

This species is currently known only from nearshore to offshore waters and have been collected by set net from 15-35 m, but was also reported to have been taken at 135 m by bottom trawl. Based on photos of landed individuals, this species probably attains close to 3 m TL. The captive female individual held for at least 15 years in the Kagoshima City Aquarium reached to 2 m TL. This wedgefish is occasionally landed at fish markets in Kagoshima Prefecture and used for culinary purpose. Reported catches of the species were very rare in the East China Sea and is apparently restricted distribution and increasing rarity indicate that the species should immediately be included in the IUCN Red List CR “Critically Endangered” category, together with other congeners (Ref. 123186).
