Taxonomy
The scientific species was first described in 1912 [5] . Earlier Mandarin dogfish confused with Cirrhigaleus australis, whose habitat is located to the south. These species have morphological and genetic differences. Cirrhigaleus australis has relatively small eyes, shorter dorsal-caudal distances and less pectoral and dorsal fins, as well as spines at their base [6] . The holotype is a male 85 cm long, found on a market in Tokyo , now lost. The specific name comes from the word lat. barbus - “antennae” [7] .
Range
Barbed whorled sharks live in the southwestern Pacific Ocean off the coasts of Japan , Taiwan and Indonesia . These sharks are found at the bottom in the upper part of the continental and island slopes at a depth of 140 to 650 m.
Description
The maximum recorded size is 126 cm. The body is stocky. The nostrils are framed by a flap of skin, forming long antennae. The snout is short and rounded. The lips are thin. The upper teeth are slightly smaller than the lower. Both the upper and lower teeth are interlocked, forming a single cutting surface, similar to a blade. At the base of the dorsal fins there are long protruding spines. Anal fin missing. The upper and lower teeth are the same size. On the caudal stem there are lateral carinae. Ventral recess on top of the caudal fin blade offline. Coloring gray-brown, belly lighter. The caudal margins of the pectoral and ventral fins have a white border [8] .
Biology
These lesser known shark breed ovoviviparity . In the litter up to 10 newborns. Males and females reach puberty at a length of 86 and 92 cm, respectively [9] . Diet probably consists of bony fishes and invertebrates . The antennae can serve to detect prey at the bottom [8] .
Human Interaction
The view is not of interest to commercial fishing. Sometimes by- catch is caught in fishing gear. Due to the long dorsal spines, these sharks can become entangled in nets and trawls. Data for the assessment by the International Union for Conservation of Nature species conservation status is not enough [9] .
