This medium sized species grows to about 42.9 cm TL and has the following set of diagnostic characters: disc 0.9-1.1 times as wide as long and with rounded outer corners, it is extremely depressed pear-shaped to broadly inverse heart-shaped (in adult male); snout angle 85-106° and larger in juveniles; snout terminally expanded as a rostral lobe that is 9-12% of preorbital snout length; further juveniles with a short, thin rostral filament; narrow interorbital distance, 2-3% of TL; inner margin of posterior pelvic lobe fused along its entire length to root of tail; length of tail from mid-vent about equal to body length from tip of rostral lobe to mid-vent in adults, but 1.5 times body length in juveniles; surface of upper and lower disc and tail entirely naked except for 2 longitudinal rows of alar thorns in adult male; the tail with 2 lateral rows of fleshy, tubular papillae; colour of upper and lower surfaces dark grayish-brown, but ventral surface somewhat darker; upper jaw with 18=26 tooth rows; monospondylous vertebral centra 25-29; scapulocoracoid subrectangular, the rear corner sharply marked; large oval anterior fenestra no anterior bridge, one very large oval postdorsal and 5 minute to small postventral fenestrae; pelvic girdle with massive ischiopubic bar with straight to weakly concave anterior and deeply concave posterior contour; prepelvic processes are very long and inclined outwards, their length from axis of pelvic girdle maximal width 3.9-5.3 times median thickness of ischiopubic bar (Ref. 95335).
一深色的平滑-皮肤 魮具有一个长又细长的尾部大于体长; 吻有角的具有基底宽的丝状突起; 具有圆角与没有大的刺或细齿的胸盘在雄性成鱼上除了翼的棘。 (参考文献 5578) 魮有分开成移动的腿状前叶的腹鳍 , 与可能融合成尾部基底的一个后面的叶。 (参考文献 5578) 全灰色-黑色或上方褐色的, 腹面颜色较淡.(参考文献 5578)
Found on the slope (Ref. 5578). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsule measures 36.0 mm long and 19.0 mm wide (Ref. 41249). Taken only by deep-trawling research vessels (Ref. 5578).
栖息于斜坡了。 (参考文献 5578) 卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘有 36.0 mm 长与 19.0 mm 宽的长。 (参考文献 41249) 只有被深-拖网研究船采。 (参考文献 5578)
