This small species (attaining about 66.5 cm DW) has the following set of characters: colour of dorsal surfaces yellowish brown, usually with variable, irregular dark blotches; tail with a very weak ventral skin fold; stinging spine(s) are relatively long (longest spine 10.3-18.6% DW); interorbital space is shallowly concave in adult males; anterior margins of pectoral fins moderately convex; cranial fontanelle (visible in dorsal view without dissection) is relatively narrow with mostly straight lateral margins; claspers of adult males 6.6-10.2% DW; predorsal length 66.6-78.8% DW; each jaw with 7 rows of teeth, with a broad median row flanked by three smaller rows on each side; pectoral-fin radials 79-85 (excluding rostral propterygial radials anterior of the eyes); total vertebral centra (including synarcual) 115-124; males mature by 42.9 cm DW (Ref. 132213).
Cross section: flattened.
Cross section: flattened.
Found from the intertidal to the uppermost continental slope (Ref. 9862, 11230). A carnivore feeding on benthic animals. Ovoviviparous (Ref. 50449). Males and females ranged in size from 24.5-61.9 and 21.4-65.6 cm DW, respectively. Five males between 42.9 and 61.9 cm DW were found to be mature and a 41.0 cm DW male was adolescent, while 18 males between 24.5 and 32.3 cm DW were immature. A female of 65.6 cm DW was found pregnant. A reported abnormal female specimen was 66.5 cm DW and weighed 5.5 kg. The largest male examined was 61.9 cm DW had a total length of 125.7 cm (Ref. 132213).
