板鰓亜鋼(サメとエイ類) (sharks and rays) >
Rajiformes (Skates and rays) >
Arhynchobatidae (Softnose skates)
Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335); panthera: The name panthera is taken from the generic name of the leopard (Felidae), recognizing
the distinctive dorsal coloration of the species, often characterized by rosettes of black spots surrounding yellow blotches.
Issue
Sometimes placed in Arctoraja.

海 底生の; 深さの範囲 51 - 258 m (Ref. 89865). Boreal, 170°E - 179°W
Pacific Ocean: Western Aleutian Islands and Petrel Bank.
Among species with subgenus Arctoraja, only B. panthera has been recorded west of 180° longitude in the Aleutian Islands, and the depth range in survey records of all skates recorded as 'B. parmifera' west of 180° longitude is 51-294 m (NMFS, AFSC, RACE survey database, 2009) (Ref. 89865).

簡単な記述
検索表 | 形態学 | 形態計測学
This species is distinguished from all other members of the subgenus Arctoraja by the following: body coloration light greenish brown, with vermiculated and round black spots and yellow blotches; distal tip of ventral marginal sinusoidal; accessory terminal 2 elongate and broad, with long spike; distal tip of axial cartilage pointed; unique COI haplotype. Bathyraja panthera is further distinguished from B. parmifera by its total thorn count 31-42 (vs. 19-36), tail thorn count 19-28 (vs. 15-23), internal carotid foramina in a single median pit (vs. foramina widely separated), distal portion of ventral marginal cartilage sinusoidal (vs. straight), accessory terminal 2 elongate with long spike (vs. broadly triangular with short spike), distal tip of axial cartilage pointed (vs. bluntly rounded), anterior portion of body longer and wider (vs. shorter and narrower), tail long (vs. short); from B. simoterus by its wide interdorsal space 1.4-3.1% TL (vs. 0.5-1.0% TL), anterior portion of body longer and wider (vs. shorter and narrower), tail longer (vs. shorter), posterior fontanelle pear-shaped (vs. narrowly elongate), internal carotid foramina in a single median pit (vs. widely separated foramina), anterior postdorsal foramen of scapulocoracoid large, others much smaller (vs. all large), ventral terminal tear-drop shaped (vs. lanceolate); from B. smirnovi by its complete series of dorsal thorns (vs. interrupted series between nuchal and tail thorns), wider interdorsal length (vs. 0.1-1.4% TL), anterior portion of body longer and wider (vs. shorter and narrower), tail longer (vs. shorter), separate anterior and posterior fontanelles (vs. single fontanelle), ventral terminal tear-drop shaped (vs. lanceolate), dorsal and ventral marginals extending to about a quarter length of dorsal terminal 2 (vs. extending farther distally to distal tip of dorsal terminal 3) (Ref. 89865).
Maximum length observed was 139 cm TL (Ref. 89865).
