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.
Taxonomic Remarks
Sometimes placed in Arctoraja.

Mô tả ngắn gọn
Khóa để định loại | Hình thái học | Sinh trắc học
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).
Body shape (shape guide): other.
Maximum length observed was 139 cm TL (Ref. 89865).
